This paper considers a new canonical duality theory for solving mixed integer quadratic programming problem. It shows that this well-known NP-hard problem can be converted into concave maximization ...

Mathematical programming with vanishing constraints (MPVC) represents a challenging class of optimisation problems where certain constraints become inactive—or “vanish”—depending on ...

Integer Linear Programming (ILP): A mathematical modelling technique that expresses decision variables as integers, with linear relationships in both the objective function and constraints ...

Either of those constraints are capable of eliminating the sub-tours. The CSV file with 400 nodes has (x,y) coordinates of depot and customer nodes, demand at customer node and the profit. The CSV ...

To address this issue, the research team proposed a Mixed Integer Programming (MIP) model ... which explicitly and effectively handles non-overlapping and safety distance constraints between cuboid ...

We are a global organization that fights inequality to end poverty and injustice. Oxfam outlines the latest in the closing of the U.S. Agency for International Development. Take action to protect U.S.

Our focus of this study is on optimizing the schedule for unit and pump operations with the aim of minimizing the number of switches over a time horizon under consideration, taking various operating ...

Abstract: In recent high-performance analog integrated circuit design, it is often required to place some cells symmetrically to a horizontal or vertical axis. Balasa et al. proposed a method of ...

This paper considers multiobjective integer programming problems involving random variables in constraints. Using the concept of simple recourse, the formulated multiobjective stochastic simple ...

Abstract: This paper describes experiences with mixed integer linear programming (MILP ... study period at each time step while respecting all system and hydraulic constraints. The problem can be ...
