The Retrograde Analysis algorithm uses multi-valued retrograde analysis to build an endgame database from different start positions, then applies this database to optimize gameplay. This approach falls under the category of Ultra-Strong solutions.
Die retrograde-analise-algoritme gebruik multi-waarde retrograde analise om 'n eindspeldatabasis vanaf verskillende beginposisies te bou, en pas dan hierdie databasis toe om spel te optimaliseer. Hierdie benadering val onder die kategorie van Ultra-Strong oplossings.
