Detailed Description

Calculate the heuristic value of the board.

The heuristic is calculated as follows:

1) three_row() is called to check if Alpha has three-ina-row.

If so, return THREE_ROW.

2) t_evaluate() is called to see if a trap exists.

If so, return the associated value.

3) Otherwise, call p_evaluate() to apply the scoring polynomial.

Function Documentation

heuristic_1 (  void   )

Calculate the heuristic value of the board. Returns: int : heuristic value of the board.

---

Variable Documentation

agr_flag_1

Aggression flag.

apply_poly_1

Apply polynomial checking?

apply_trap_1

Apply trap 1 checking? Value for apply_trap_1: 0 - do not apply trap check. 1 - apply trap1. 2 - apply trap1 and trap2.
