Wemmerlöv corrected PPB + LALB

Class: ULSAlgorithms.Heuristics.WemmerlovModifiedPpbLookAheadLookBackSolver

Family: Look-ahead / look-back
Time: O(T)
Memory: O(T)
Applicability: Stationary costs; strictly positive demand

Description

Wemmerlöv corrected PPB + LALB is a fast ULS heuristic in the Look-ahead / look-back family. It constructs a feasible replenishment plan without claiming an optimality proof. Use it only when the documented applicability conditions match the instance.

Minimal API

IUlsSolver solver = new WemmerlovModifiedPpbLookAheadLookBackSolver();
UlsSolveResult result = solver.Solve(problem);
