virtual void idol::Callback::submit_heuristic_solution ( const PrimalPoint &  t_solution )

protectedvirtualinherited

Submits a new heuristic solution

terminate()

void idol::Callback::terminate ( )

protectedinherited

Asks the optimizer to terminate the optimization process as soon as possible

time()

const Timer & idol::Callback::time ( ) const

protectedinherited

Returns the current time

Returns

the optimizer's time
