[gecode-users] scheduling problem, tow branchers, order of branching

[Wu Shaowei]

Hi to everyone on the ML,

I am working on a scheduling problem,I have two variable array:

*IntVarArray QuantityTask*;

*SetVarArray WorkTimeTask*;


ant two branchers:

branch(*this,QuantityTask,INT_VAR_NONE(),INT_VAL_MIN());

assign(*this,WorkTimeTask,SET_ASSIGN_MIN_INC());


Asume I have 2 tasks, Gecode's default enumration order is:

(branch)QuantityTask[0]-->(branch)QuantityTask[1]-->(assign)WorkTimeTak[0]-->(assign)WorkTimeTask[1],

*how can I achieve this:*

*(branch)QuantityTask[0]-->(assign)WorkTimeTak[0]-->(branch)QuantityTask[1]-->(assign)WorkTimeTask[1]*


I have read MPG 8.14 Executing code between branchers,
and http://www.gecode.org/pipermail/users/2015-April/004669.html,
but has not a clue.

Thank you!

Best,
Wu Shaowei
