Then I found the TSP example and would like to ask for help:<br /><br />(1)<br />http://www.gams.com/modlib/libhtml/tsp4.htm<br />Why is the cuts added after the <br />"solve assign using mip minimizing z;"<br />line, yet it's still effective in adding cuts into the current model?<br /><br />(2)<br />Can you recommend some website / papers where I can finds ways to implement VRP with GAMS? The constraints are really difficult to work with.<br /><br />Best,<br /><br /><br />JimJimhttps://www.blogger.com/profile/13199607064559637395noreply@blogger.com
