Dual Simplex Method
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
The dual-simplex method is an algorithm used in linear programming to solve optimization problems. It is a variant of the simplex method designed to efficiently handle cases where the initial solution might be infeasible for the primal problem but feasible for the dual. The approach iteratively pivots between feasible solutions of the dual problem to find the optimal solution of the primal, often improving computational efficiency in certain problem structures.
