[gecode-users] Update function

[Zhu Zichen's cse]

Dear All,
          For variables, why do we have to use update function when we
copying? Why cannot I simply use rel(*this,x==_x)? And there are problems
when I use update function to update a global variable from another global
variable. What should I do when I update global variables?


Best Regards,
Zichen Zhu
