This is a very fast method, while simulated annealing, tabu search etc. is typically applied when no fast methods are known. Btw. your description of the simplex method does not make much sense to me.Erwin Kalvelagenhttps://www.blogger.com/profile/09496091402502236997noreply@blogger.comtag:blogger.com,1999:blog-593563533834706486.post-5286719544109076602009-06-21T06:07:25.777-04:002009-06-21T06:07:25.777-04:00As I understand it (I could be wrong), equations a...As I understand it (I could be wrong), equations are used to solve planning problems.<br />The constraints of a planning problem are written as equations and the optimal values for the variables are calculated.<br /><br />But indeed, if you're not tackling a planning problem with your equation, drools-solver is irrelevant. I got linked to this blog from a planning problem blog and I am trying to harvest positive criticism (or even patches) of other experts on my planning problem framework.Geoffrey De Smethttps://www.blogger.com/profile/10118333179703404539noreply@blogger.comtag:blogger.com,1999:blog-593563533834706486.post-74648832425783851452009-06-20T11:26:15.413-04:002009-06-20T11:26:15.413-04:00That does not look very relevant to solving system...That does not look very relevant to solving systems of linear equations, or am I missing something?Erwin Kalvelagenhttps://www.blogger.com/profile/09496091402502236997noreply@blogger.comtag:blogger.com,1999:blog-593563533834706486.post-75245346787443868622009-06-20T10:12:15.496-04:002009-06-20T10:12:15.496-04:00Have you taken a look at drools-solver?

What where the results given the limited time?Geoffrey De Smethttps://www.blogger.com/profile/10118333179703404539noreply@blogger.com
