Commercial branch and bound codes for solving the general mixed integer linear programming problem commence by solving the linear programming relaxation of the submitted problem, terminating if the relaxation is unbounded. It is assumed that the submitted problem is either unbounded or has no feasible ...
When a nonlinear programming model is unbounded, one can be running into numerical problems. In particular, issues such scaling, starting points, tolerances and other numerical issues can be the problem. The bounding technique above has been shown in the authors work. To be useful but on occasio...
In this paper, the linear functional state bounding problem, which is considered in [25], is extended to the singular system with unbounded delay. Firstly, some conditions are presented to guaranteed positivity, regularity, impulse‐free, and the component﹚ise bound for the state vector of the...
The correct option is (d). It is under linear programming in which if the primal has an unbounded solution or it is unbounded then dual unbounded... See full answer below.
Based on dissertating the study of transportation problem,some concepts were proposed such as the multiple optimal solutions,the numbered multiple optimal solutions,the unnumbered multiple optimal solutions, the narrow-sense multiple optimal solutions and the broad-sense multiple optimal solutions etc. 在...
We apply the method known as simulated annealing to the following problem in convex optimization: Minimize a linear function over an arbitrary convex set, ... KS Vempala - 《Mathematics of Operations Research》 被引量: 184发表: 2006年 Non-Convex Optimization A stochastic search technique called ...
We show that the conjugacy problem is solvable in [finitely generated free]-by-cyclic groups, by using a result of O. Maslakova that one can algorithmically find generating sets for the fixed subgroups of free group automorphisms, and on... R Henstock,P Muldowney,VA Skvortsov - 《Bulletin ...
We discuss a Krylov–Schur like restarting technique applied within the symplectic Lanczos algorithm for the Hamiltonian eigenvalue problem. This allows us... P Benner,Heike Fa?bender,M Stoll - 《Linear Algebra & Its Applications》 被引量: 37发表: 2011年 Effects of a graduate-level interprofessi...
Paralleled to the combined homotopy interior point method for nonlinear programming problems, a homotopy method for solving a class of nonconvex Brouwer fixed point problem is also given. In 1984, Karmarkar presented a polynomial-time ... Y Bo,G Feng - Springer US 被引量: 14发表: 1998年 A...
