Implementing Hybrid Solution Algorithms using Xpress-Mosel

Monday, 10:30am-11:20am
Dash Optimization
Nikhilesh Khotekar, OR Consultant

ABSTRACT


This tutorial focuses on developing and deploying complex hybrid algorithms using Xpress-Mosel and Xpress-IVE.

  • Xpress-Mosel: the next generation language for modeling and solving problems combines features of both modeling and programming languages. Since there is no separation between a modeling statement and a procedure that solves the problem, one can program complex solution algorithms by interlacing modeling and solving statements in Mosel.
  • Xpress-IVE: a visual development environment for developing Mosel models. Using Xpress-IVE one can analyze LP/MIP/QP/SLP problems by visualizing the problem matrix, branch-and-bound search tree and optimization results. It provides visual clues to develop and fine-tune search strategies.
