Detailed Description
Function object expressing an aspiration criteria.
An aspiration criteria is a criteria used to override the tabu list. When the aspiration criteria is met a move is made even if it's in the tabu-list
Aspiration critera can be chained so a criteria can decorate another criteria

| void mets::aspiration_criteria_chain::accept | ( | feasible_solution & | fs, |
| move & | mov, | ||
| gol_type | evaluation | ||
| ) | [inline, virtual] |
This is a callback function from the algorithm that tells us that a move was accepted.
You can use this function to update the aspiration criteria based on the current search status. (e.g. record the best cost for a best ever criteria)
- Parameters:
-
fs The current working solution (after applying move). mov The accepted move (the move just made).
- Returns:
- True if the move is to be accepted.
Reimplemented in mets::best_ever_criteria.

| bool mets::aspiration_criteria_chain::operator() | ( | feasible_solution & | fs, |
| move & | mov, | ||
| gol_type | evaluation | ||
| ) | const [inline, virtual] |
The function that decides if we shoud accept a tabu move.
- Parameters:
-
fs The current working solution (before applying move). mov The move to be made (the move that is being evaluated).
- Returns:
- True if the move is to be accepted.
Reimplemented in mets::best_ever_criteria.

purposely not implemented (see Effective C++)
| void mets::aspiration_criteria_chain::reset | ( | ) | [inline, virtual] |
A method to reset this aspiration criteria chain to its original state.
