for O(3) Phi^{4} spin model 
Spins with three components: S=(S^{x},S^{y},S^{z}) local field : h_{local}=(h_{local}^{x},h_{local}^{y},h_{local}^{z}) Energy=S.h_{local}=h_{local}.x.cos(z) P(x)=e^{Energy/T}.dx.dz.du = e^{ h.x.y  x2 landa.(x21)2}.dx.dy.du 
The Alias Walker Hasting algorithm (AWH) uses the rejection method with a function consisting of n steps (see figures and article for more details) 
1.  To use the Alias Walker Hasting algorithm you must have :  


2.  AND you must have the tables in the file "O3_Phi4_walker.res". Two choices: . You can choose to download the file O3_Phi4_walker.res already done or make one with create_O3_Phi4_walker.c.
