Simple API

Simple API

Most users need only four public types.

UlsProblem

Input data for one deterministic ULS instance.

var problem = new UlsProblem(
    demands,
    setupCosts,
    unitProductionCosts,
    holdingCosts);

All vectors have length Horizon.

IUlsSolver

The common strategy interface.

IUlsSolver solver = new WagnerWhitinSolver();
var result = solver.Solve(problem);

Every algorithm exposes:

Member	Meaning
Name	readable algorithm name
Kind	exact or heuristic
Solve(problem, cancellationToken)	solve the instance

UlsSolveResult

The common result wrapper.

Member	Meaning
Status	optimal, feasible, infeasible, failed, …
ObjectiveValue	total cost when a solution exists
Solution	detailed production plan
Message	optional diagnostic information

UlsSolution

The detailed plan contains production quantities, ending inventories, setup decisions and cost components.

Advanced APIs

You only need the advanced layer when using solver selection, mathematical formulations, cutting-plane reports or custom execution backends. Those types remain fully documented in the generated class/namespace reference but are intentionally kept out of the basic workflow.

This split is deliberate: simple API first, implementation API second.
