Author: Jaroslav Fowkes and Nick Gould

GALAHAD [1] is a suite of open-source routines for large-scale continuous optimization. Currently there are three packages designed to solve linear programming problems, or to find a feasible point within a polyhedral set (one defined by a finite number of linear inequalities).

Contents

• LPA - linear programming using the simplex method
• LPB - linear programming using an interior-point method
• WCP - find a well-centered point within a polyhedral set
