The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

For years, John Alle complained to Los Angeles officials about homelessness. Now, fed up, he’s trying to make a dent in the problem on his own. For years, John Alle complained to Los Angeles officials ...

This paper proposes an exact method to solve an integer indefinite quadratic bilevel problem with multiple objectives at the upper level, where the objective functions at both levels are a product of ...

When WarnerMedia and Discovery Inc. merged back in 2022, the rationale was that the combination would put the companies in a better position to compete against Netflix, Disney and others that were ...

Abstract: In the present paper,attention has been given to the study of fuzzy linear fractional programming problem(FLFPP) using sign distance ranking method,where ...

Linear programming (LP) solvers are crucial tools in various fields like logistics, finance, and engineering, due to their ability to optimize complex problems involving constraints and objectives.

We study a class of integer bilevel problems, the so-called Integer Linear Multiplicative Bilevel Problem, ILMBP, where the constraints are linear and both the upper level problem and the lower level ...

ABSTRACT: In this paper, a new statistical averaging technique is proposed for finding an optimal solution to a multi-objective linear fractional programming problem (MOLFPP) and multi-objective ...
