Constructor Detail

TimingProblem

public TimingProblem(Problem problem)
Decorates the specified problem to collecting objective function evaluation timing data.

Parameters:
problem - the problem to decorate
Method Detail

getName

public String getName()
Description copied from interface: Problem
Returns the user-friendly name for this problem.

Specified by:
getName in interface Problem
Returns:
the user-friendly name for this problem

getNumberOfVariables

public int getNumberOfVariables()
Description copied from interface: Problem
Returns the number of decision variables defined by this problem.

Specified by:
getNumberOfVariables in interface Problem
Returns:
the number of decision variables defined by this problem

getNumberOfObjectives

public int getNumberOfObjectives()
Description copied from interface: Problem
Returns the number of objectives defined by this problem.

Specified by:
getNumberOfObjectives in interface Problem
Returns:
the number of objectives defined by this problem

getNumberOfConstraints

public int getNumberOfConstraints()
Description copied from interface: Problem
Returns the number of constraints defined by this problem.

Specified by:
getNumberOfConstraints in interface Problem
Returns:
the number of constraints defined by this problem

evaluate

public void evaluate(Solution solution)
Description copied from interface: Problem
Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.

Specified by:
evaluate in interface Problem
Parameters:
solution - the solution to be evaluated

newSolution

public Solution newSolution()
Description copied from interface: Problem
Returns a new solution for this problem. Implementations must initialize the variables so that the valid range of values is defined, but may leave the actual value at a default or undefined state.

Specified by:
newSolution in interface Problem
Returns:
a new solution for this problem

clear

public void clear()
Clears any timing data collected.


getTime

public double getTime()
Returns the time, in seconds, expended on objective function evaluation.

Returns:
the time, in seconds, expended on objective function evaluation

close

public void close()
Description copied from interface: Problem
Closes any underlying resources used by this problem. Once closed, further invocations of any methods on this problem may throw exceptions.

Specified by:
close in interface Problem
