Mar 9, 2014 at 23:33 | comment | added | mathemagic | Thank you both. The Johnson's algorihm, as I find it, usually has the order of variables determined in advance. That leads to tight examples for 2/3 ratio such as $(x \vee \neg y) \wedge (\neg x \vee y) \wedge \neg y$ where we set $x=1, y=0$. However, such example doesn't work for the algorithm described. Do you by chance see, how to adapt it? | |
