Interface Solver

All Known Implementing Classes:

ExhaustiveSolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Solver

Searches the portfolios a SolveProblem allows and returns the trade-off frontier and the recommended option. A solver must be deterministic: the same problem gives the same solution, with ties broken by MetroPortfolio.key().

Method Details

solve

DesignSolution solve(SolveProblem problem)

Parameters:

problem - the candidates, objectives, constraints, weights and size limits

Returns:

the solution; never null, and DesignSolution.isFeasible() is false when nothing satisfies the constraints
