A smoothing method for mathematical programs with

complementarity constraints

报告摘要

This paper presents a smoothing method for mathematical programs with

complementarity constraints (MPCC) based on the integral of the sigmoid

function. The original MPCC is reformulated as a standard smooth

approximation minimization problem with a smooth parameter and the

approximate solution of the MPCC is obtained by solving a series of the

smooth subproblems with the smooth parameter approaching to zero. The

characterizations of the linear independence constraints qualification (LICQ),

the KKT condition and the second-order sufficient condition for the smooth

approximation problem are established under several assumptions on the

original MPCC, which ensures the existence of KKT stationary solutions to the

smooth subproblems. Furthermore, it is proven that the accumulation point of

sequence of KKT stationary solutions to the smooth subproblems is a

C-stationary point of the MPCC under the weaker assumptions, without

asymptotically weakly nondegenerate (AWN) condition. At last, we implement

numerical experiments to test the efficiency of the proposed smoothing

method by solving some typical problems in MacMPEC database. The

reported numerical results show that the proposed smoothing method is

promising by comparing with the other related method and the optimal values

in MacMPEC database.

A smoothing method for a class of generalized Nash equilibrium

problems

报告摘要

The generalized Nash equilibrium problem is an extension of the standard

Nash equilibrium problem where both the utility function and the strategy

space of each player depend on the strategies chosen by all other players.

Recently, the generalized Nash equilibrium problem has emerged as an

effective and powerful tool for modeling a wide class of problems arising in

many fields and yet solution algorithms are extremely scarce. In this paper,

using a regularized Nikaido-Isoda function, we reformulate the generalized

Nash equilibrium problem as a mathematical program with complementarity

constraints (MPCC). We then propose a suitable method for this MPCC and

under some conditions, we establish the convergence of the proposed method

by showing that any accumulation point of the generated sequence is a

M-stationary point of the MPCC. Numerical results on some generalized Nash

equilibrium problems are reported to illustrate the behavior of our approach.

Efficient sparse Hessian based algorithms for the clustered lasso

problem

报告摘要

In this talk, we focus on solving the clustered lasso problem, which is a least

square problem with the L1-type penalties imposed on both the coefficients

and their pairwise differences to learn the group structure of the regression

parameters. This work first reformulates the clustered lasso regularizer as a

weighted sorted-lasso regularizer, which takes much lower computational cost

than the original one. This work then proposes an inexact semismooth Newton

augmented Lagrangian (Ssnal) algorithm to solve this equivalent reformulation

or its dual depending on whether the sample size is larger than the dimension

of the features. Comprehensive results on the global convergence and local

convergence rate of the Ssnal algorithm are established. For the purpose of

exposition and comparison, this work also summarizes/designs several

first-order methods that can be applied to solve the problem under

consideration. The numerical experiments show that the Ssnal algorithm

substantially outperforms the best alternative algorithms for the clustered lasso

problems. [This is a joint work with Meixia Lin, Defeng Sun and Kim-Chuan

Toh.]

Recent Progress on Non-Symmetric Cones

报告摘要

Non-symmetric cones have long been mysterious to optimization

researchers because of no unified analysis technique to handle these cones.

Nonetheless, by looking into symmetric cones and non-symmetric cones, it is

still possible to find relations between these kinds of cones. More specifically,

projections onto cones, spectral decomposition associated with cones,

non-smooth analysis regarding cone-functions and cone-convexity are the

bridges between symmetric cone programs and non-symmetric cone

programs. This talk is to present some recent progress on non-symmetric

cones in views of these items. We believe that all the aforementioned results

are very crucial to subsequent study on non-symmetric conic programming.

A Class of Smooth Approximation Methods for Solving Chance

Constrained Optimization Problems

报告摘要

Many practical problems with important sig, such as calculation of risk

value in risk optimization, systemic scheduling problem with new energy and

power, route location processing in mobile networks, and so on, belong to

probabilistic constrained optimization problem, which requires that random

constraints should be satisfied with a large enough probability Simultaneously.

Representative methods are convex conservative approximation method, D.C.

approximation method, smooth approximation method, etc. In view of

non-differentiability of probability constrained functions, a class of smooth

approximation methods for solving chance constrained optimization problems

is discussed in this paper. Theoretical framework and algorithm design are

built. Firstly, a class of smooth approximation functions to characteristic

function is defined, and the corresponding smooth approximation problems

(På ) are established. Secondly, sequence convex approximation algorithm is

proposed to solve the smooth approximation problems. Finally, numerical

results based on Pinar-Zenios smooth sum function and Sigmoid function are

reported respectively. The numerical results illustrate that the proposed

smooth approximation method is effective for solving some chance

constrained optimization problems.

A neural network based on two discrete-type complementarity

functions for solving SOCQP and SOCCVI

报告摘要

This paper focuses on solving the quadratic programming problems with

second-order cone constraints (SOCQP) and the second-order cone

constrained variational inequality (SOCCVI) by using the neural network. More

specifically, a neural network model based on two discrete-type

complementarity functions associated with second-order cone, which are

discovered recently, is proposed to deal with the Karush-Kuhn-Tucker (KKT)

conditions of SOCQP and SOCCVI. Under some condition, the Lyapunov

stability, asymptotical stability, and exponential stability is established,

respectively. Some simulation results are provided to demonstrate the

effectiveness of the proposed neural network.

A smoothing SAA method for a stochastic mathematical program

with second-order cone complementarity constraints

报告摘要

To solve a stochastic mathematical program with second order cone

complementarity constraints, we suggest a smoothing SAA approach. We first

construct a surrogate SAA problem with a projection operator. Smoothing

technique is then employed. Under some mild assumptions, we proved that

our approach convergence to the proposed C-stationary almost surly, and with

additional assumptions, M-stationary and S-stationary can be achieved almost

surly.

Properties associated with the epigraph of the 1 *l *norm function of

projection onto the nonnegative orthant

报告摘要

This paper studies some properties associated with a closed convex cone ê1+ ,

which is defined as the epigraph of the 1 *l *norm function of the metric

projection onto the nonnegative orthant. Specifically, this paper presents some

properties on variational geometry of ê1+ such as the dual cone, the tangent

cone, the normal cone, the critical cone and its convex hull, and others; as well

as the differential properties of the metric projection onto ê1+ including the

directional derivative, the B-subdifferential, and the Clarke’s generalized

Jacobian. These results presented in this paper lay a foundation for future

work on sensitivity and stability analysis of the optimization problems over ê1+ .

A study of a DC penalty formulation for solving a class of quadratic

programs with linear complementarity constraints

报告摘要

In this paper, we study a type of DC penalty formulation based on a piecewise

linear penalty function for computing stationary solutions of quadratic

programs with linear complementarity constraints (QPCCs). Relationships

between the stationary points of the QPCC and those of the penalty

formulation, especially for fixed values of the penalty parameter, are discussed.

qualification, we derive continuity for the feasible solution set mapping and the

optimal solution set mapping against variation of the parameter over Banach

space. In comparison with the existing stability results for parametric

programming, our results are established without any assumption on

continuous differentiability of the underlying functions or reducibility of K.

The results established are applied to stability analysis of a distributionally

robust optimization、stability analysis of a stochastic quasi-variational

inequality and convergence analysis of a global algorithm for a nonconvex

QCQP.

An efficient Hessian based algorithm for solving large-scale sparse

group Lasso problems

报告摘要

The sparse group Lasso is a widely used statistical model which encourages

the sparsity both on a group and within the group level. In this paper, we

develop an efficient augmented Lagrangian method for large-scale

non-overlapping sparse group Lasso problems with each subproblem being

solved by a superlinearly convergent inexact semismooth Newton method.

Theoretically, we prove that, if the penalty parameter is chosen sufficiently

large, the augmented Lagrangian method converges globally at an arbitrarily

fast linear rate for the primal iterative sequence, the dual infeasibility, and the

duality gap of the primal and dual objective functions. Computationally, we

derive explicitly the generalized Jacobian of the proximal mapping associated

with the sparse group Lasso regularizer and exploit fully the underlying second

order sparsity through the semismooth Newton method. The efficiency and

robustness of our proposed algorithm are demonstrated by numerical

experiments on both the synthetic and real data sets.

The optimization problem in MIMO radar transmit beampattern

matching design

报告摘要

In this talk, a novel transmit beampattern matching design method is proposed

for a multiple-input multiple-output (MIMO) radar system. Whereas previous

approaches first solve the correlation matrix R, then use R to design the

transmit signal S, the proposed one-step method obtains the transmit signal S

directly through solving the waveform matrix P. Since MIMO radar transmit

beampattern matching design is an inverse problem of the transmit

beampattern, in this paper, we first discuss some important properties of the

transmit beampattern and standardize the beampattern matching design

problem. We then theoretically explain the value of the signal waveform matrix

P, followed by an unconstrained optimization problem to solve P. Numerical

examples demonstrate the advantages of the proposed one-step method for

the MIMO radar transmit beampattern matching design problem, including

uniform and non-uniform linear arrays.

New Constraint Qualifications and Optimality Conditions for

Second Order Cone Programs

报告摘要

We introduce three new constraint qualifications for nonlinear second order

cone programming problems that we call constant rank constraint qualification,

relaxed constant rank constraint qualification and constant rank of the

subspace component condition. Our development is inspired by the

corresponding constraint qualifications for nonlinear programming problems.

We provide proofs and examples that show the relations of the three new

constraint qualifications with other known constraint qualifications. In particular,

the new constraint qualifications neither imply nor are implied by Robinson's

constraint qualification, but they are stronger than Abadie's constraint

qualification. First order necessary optimality conditions are shown to hold

under the three new constraint qualifications, whereas the second order

necessary conditions hold for two of them, the constant rank constraint

qualification and the relaxed constant rank constraint qualification.
