Ultimate tic-tac-toe simple rules, ultimate tic-tac-toe lacks any simple heuristic evaluation function. This function is necessary in minimax, for it determines how good a specific position is. Although elementary evaluation functions can be made for ultimate tic-tac-toe by taking into account the number of local victories, these largely overlook positional advantage that is much harder to quantify. Without any efficient evaluation function, most typical computer implementations are weak, and therefore there are few computer opponents that can consistently outplay humans. However, artificial intelligence algorithms that don't need evaluation functions, like the Monte Carlo tree-search algorithm, have no problem in playing this game.
The Humans (video game) sound effects or a music track, unlike the PC and Amiga versions, which utilize both simultaneously. Following the success of the original release, an expansion pack containing 80 additional levels was released in 1992 under the name "Humans 2: The Jurassic Levels" in the UK and "The Humans: Insult to Injury" in the United States. in 1993, the two games were combined and released for both Amiga and DOS under the name "Humans 1 and 2" and included English, French, German, Italian and Spanish versions. The DOS was distributed on a CD-ROM and was improved in several ways, including adding
