QUESTION

Does OR-tools CP-SAT solver supports "reflection" methods such as x.Min() and x.Max()?

Asked 2021-Feb-18 at 18:40

I'm porting my old (from 2010) OR-tools CP solver models to the CP-SAT solver (in Python3). There are quite a few differences between these systems, but most are quite easy to port to the CP-SAT solver.

However, one thing I haven't found in the CP-SAT solver documentation is the "reflection" methods that the old CP solver supports, such as getting lower/upper bounds of a decision variables. E.g.

Understanding minzinc

Asked 2020-Nov-25 at 20:06

I'm newbie in CP. I am trying to solve my problem and I used Hakan's code as example from here http://hakank.org/minizinc/scheduling_with_multiple_workers.mzn

I dont know what exactly mean this part of code, where machine[t]=m. Could anyone explain me this part?

(machine[t]=m) is a Boolean expression converted to 1, if machine[t] is equal to m. Otherwise, it is 0.

So, (machine[t]=m)*(tt in start_time[t]..end_time[t]) is selecting all memory values to be summed-up which belong to the machine and time of the outer forall loops.
