Detailed Description

Interface for algorithms that approximate a solution to a pass::problem. Subclasses need only implement optimise.

Constructor & Destructor Documentation

optimiser()

pass::optimiser::optimiser

(

const std::string &

name

)

Initialises an optimiser with its own name

Member Function Documentation

optimise()

virtual optimise_result pass::optimiser::optimise ( const pass::problem &  problem )

pure virtual

Optimises problem, storing the result and performance characteristics of the optimisation in the returned optimise_result.

Implemented in pass::parallel_swarm_search, pass::particle_swarm_optimisation, and pass::random_search.

Here is the caller graph for this function:

Member Data Documentation

acceptable_fitness_value

double pass::optimiser::acceptable_fitness_value

The optimiser will stop early if it finds a agent that evaluates to a value less than or equal to acceptable_fitness_value.

Initialised to -infinity.

maximal_duration

std::chrono::nanoseconds pass::optimiser::maximal_duration

The maximal elapsed time before the optimiser stops.

Initialised maximum time std::chrono::system_clock::duration::max().

maximal_evaluations

arma::uword pass::optimiser::maximal_evaluations

The maximal number of evaluations before the optimiser stops.

Initialised to the maximum value representable with arma::uword.

maximal_iterations

arma::uword pass::optimiser::maximal_iterations

The maximal number of iterations before the optimiser stops.

Initialised to the maximum value representable with arma::uword.

name

const std::string pass::optimiser::name

Identify every optimiser with its own name
