SolverFactory

trait SolverFactory extends AnyRef

Overview

Solver factory is an essence a collection of lazily initialized strategy singletons solving some (any) problem in context of the Mahout project.

We intend to use it _mainly_ for problems that are super-linear problems, and often involve more than one argument (operand).

The main method to probe for an available solver is RootSolverFactory.getSolver.

    Note to callers

    Due to Scala semantics, it is usually not enough to request a solver via merely 

    val s:SolverType = backend.getSolver

    but instead requires an explicit solver tag, i.e.: 

    val s = backend.getSolver[SolverType]
