ME Table: Zadeh From:   Jørn Thyssen Address:   jth@gnubg.org Date:   28 March 2004 Subject:   Re: Take that Zadeh table and throw it in the trash Forum:   GammOnLine I've just rechecked Zadeh's formulae from his 1977 paper with my implementation in gnubg, and found a minor "bug", namely that I used the lower gammon-ratio[1] for 1-away pre-Crawford scores. After fixing this the table looks like this: 1-away 2-away 3-away 4-away 5-away 6-away 7-away 1-away 50.0000 68.7500 75.5625 82.2187 84.7359 89.4758 91.2213 2-away 31.2500 50.0000 60.3017 67.7106 74.7389 80.5867 84.6234 3-away 24.4375 39.6983 50.0000 57.4482 65.0828 71.5718 76.5747 4-away 17.7813 32.2894 42.5518 50.0000 57.7182 64.4691 70.0621 5-away 15.2641 25.2611 34.9172 42.2818 50.0000 56.8277 62.7639 6-away 10.5242 19.4133 28.4282 35.5309 43.1723 50.0000 56.2111 7-away 8.7787 15.3766 23.4253 29.9379 37.2361 43.7889 50.0000 Jørn [1] Zadeh works with two gammon ratios: G1 for the doubler and G2 for the doublee. Generally G1>G2. For some reason I used G2 for the 1-away pre- Crawford scores rather than G1.   Did you find the information in this article useful?           Do you have any comments you'd like to add?
