Detailed Description

template<typename SearchSpace>
class shark::AbstractMultiObjectiveOptimizer< SearchSpace >

base class for abstract multi-objective optimizers for arbitrary search spaces.

Models an abstract multi-objective optimizer for arbitrary search spaces. The objective space is assumed to be \( \mathbb{R}^m\).

Template Parameters

SearchSpace The search space of the optimizer.

Member Function Documentation

template<typename SearchSpace >

virtual void shark::AbstractMultiObjectiveOptimizer< SearchSpace >::init ( const ObjectiveFunctionType & function )

inlinevirtual

Initializes the optimizer for the supplied objective function.

Tries to sample an initial starting point. If the function does not implement this feature, an exception is thrown. Otherwise, the call is dispatched to the pure-virtual function.

Parameters

function The function to be initialized for.

Exceptions

shark::Exception if the function does not feature the proposal of starting points.

Implements shark::AbstractOptimizer< SearchSpace, shark::RealVector, std::vector< ResultSet< SearchSpace::PointType, shark::RealVector > > >.
