Lambda-search code

• version 2.0: (Dec 21, 2000). Completely re-written Java-version of the lambda-code, including a Go-moku/tic-tac-toe implementation.This new version is modular, distinguishing cleanly between the lambda-algorithm, the concrete "search engine" (here: alpha-beta), and the concrete game being played. In addition, the (large version of the) code handles disproofs better. The code is illustrated on a 4x4 and 3x3 (tic-tac-toe) board, and the code is deliberately simple (procedure-oriented).
• version 1.0: (Dec 12, 2000). This version (in Java pseudo-code) is probably a little imprecise and will be replaced by a new version very soon
