OjAlgoSolver (Relix API (all))

All Implemented Interfaces:: MathProgrammingSolver

public final class OjAlgoSolver extends Object implements MathProgrammingSolver

The shipped MathProgrammingSolver: ojAlgo's deterministic branch-and-bound.

Every ojAlgo type in the build is named in this one class. Instances hold no state and are therefore thread-safe; a model is built per solve.

  public SolverResult solve(LinearProgram program)
  
  Description copied from interface: MathProgrammingSolver
  
  Solves a program.
  Three outcomes, and a provider is expected to distinguish them rather than collapse the last two: an optimal assignment (SolverResult.Solved), a program proved to have none (SolverResult.Infeasible), and a search that did not decide — failed, cut off, unbounded, malformed (SolverResult.Undetermined, carrying a short reason). Infeasibility is a normal answer the engine acts on; an undecided search is an error it reports, because a query cannot honestly say "no rows" about a question nobody answered. An exception means the provider itself broke.
  
  Specified by:
  
  solve in interface MathProgrammingSolver
  
  Parameters:
  
  program - the program to solve; must not be null
  
  Returns:
  
  what the solver concluded; never null
