Smoothing Approximation to the Square-Order Exact Penalty Functions for Constrained Optimization

Journal of Applied Mathematics, 2013
A method is proposed to smooth the square-order exact penalty function for inequality constrained optimization. It is shown that, under some conditions, an approximately optimal solution of the original problem can be obtained by searching an ...

Approximation Algorithm for the Single Machine Scheduling Problem with Release Dates and Submodular Rejection Penalty

Mathematics, 2020
In this paper, we consider the single machine scheduling problem with release dates and nonmonotone submodular rejection penalty. We are given a single machine and multiple jobs with probably different release dates and processing times. For each job, it

Exact penalty function and asymptotic strong nonlinear duality in integer programming [PDF]

, 2004
In this paper, a logarithmic-exponential penalty function with two parameters for integer programming is discussed. We obtain the exact penalty properties and then establish the asymptotic strong nonlinear duality in the corresponding logarithmic ...

A family of global convergent inexact secant methods for nonconvex constrained optimization

Journal of Algorithms & Computational Technology, 2018
We present a family of new inexact secant methods in association with Armijo line search technique for solving nonconvex constrained optimization. Different from the existing inexact secant methods, the algorithms proposed in this paper need not compute ...

Pattern-Multiplicative Average of Nonnegative Matrices: When a Constrained Minimization Problem Requires Versatile Optimization Tools

Mathematics, 2022
Given several nonnegative matrices with a single pattern of allocation among their zero/nonzero elements, the average matrix should have the same pattern as well.

Exact Penalty Functions for Nonlinear Integer Programming Problems [PDF]

Journal of Optimization Theory and Applications, 2010
The authors first find a set of sufficient conditions under which the nonlinear problem \(\min \{ f(x) \, : \, x\in W \}\) has the same minimum point(s) as each member of the family \(\min \{ f(x)+\phi (x, \varepsilon) \, : \, x\in X ...
