Space-Time Tradeoff
Home * Programming * Space-Time Tradeoff
Space-Time Tradeoff refers to providing knowledge, information or data, where memory size competes with computation time. This tradeoff is a frequent issue in computer chess programming, for instance low level stuff to calculate or lookup single populated bitboards by square index, or a distance between two squares. Lookup tables are non-volatile tables or initialized once at program startup, various hash tables and caches. Space-time tradeoff is also an issue in determining (almost) perfect knowledge from interior node recognizers by retrograde analysis, that is the application of endgame bit- or tablebases and various compression techniques.
