Effective Hand Strength (EHS) is a poker algorithm conceived by computer scientists Darse Billings, Denis Papp, Jonathan Schaeffer and Duane Szafron that has been published for the first time in a It has since then been considered as a reference in the realm of poker artificial intelligence and has been the basis of further research such as: * * * == Algorithm == The algorithm is a numerical approach to quantify the strength of a poker hand where its result expresses the strength of a particular hand in percentile (i.e. ranging from 0 to 1), compared to all other possible hands. The underlying assumption is that an Effective Hand Strength (EHS) is composed of the current Hand Strength (HS) and its potential to improve or deteriorate (PPOT and NPOT): : where: * is the Effective Hand Strength * is the current Hand Strength (i.e. not taking into account potential to improve or deteriorate, depending on upcoming table cards * is the Negative POTential (i.e. the probability that our current hand, if the strongest, deteriorates and becomes a losing hand) * is the Positive POTential (i.e. the probability that our current hand, if losing, improves and becomes the winning hand) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Poker Effective Hand Strength (EHS) algorithm」の詳細全文を読む スポンサード リンク
