Member Function Documentation

◆ checkReachability()

bool XMLCallsBranin::checkReachability ( const vectord &  query)
inlinevirtual

This function checks if the query is valid or not.

It can be used to introduce arbitrary constrains. Since the Gaussian process assumes smoothness, constrains are managed by the inner optimizer (e.g.:DIRECT), being highly time consuming. If the constrain is very tricky, DIRECT will need much more function evaluations.

Note: This function is experimental. Thus it is not made pure virtual. Using it is completely optional.

Parameters
querypoint to be evaluated.
Returns
boolean value showing if the the function is valid at the query point or not.

Reimplemented from bayesopt::BayesOptBase.

Definition at line 145 of file branin_xml.cpp.

◆ evaluateSample()

double XMLCallsBranin::evaluateSample ( const vectord &  query)
inlinevirtual

Function that defines the actual function to be optimized.

This function must be modified (overriden) according to the specific problem.

Parameters
querypoint to be evaluated.
Returns
value of the function at the point evaluated.

Implements bayesopt::BayesOptBase.
