Method Details

getName

public String getName()

Description copied from interface: Problem

Returns the user-friendly name for this problem.

Specified by:

getName in interface Problem

Overrides:

getName in class AbstractProblem

Returns:

the user-friendly name for this problem

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 typically leave the actual value at a default or undefined state.
