Hi Riyadh,

There are two probe_sched/5 -- one in lib(ic_probing_for_scheduling), 
the other in lib(probing_for_scheduling), which is the older version 
that uses the old lib(fd) rather than lib(ic). You did not say which one 
you are using -- you should use the ic version (ic_probing_for_scheduling).

I compiled the example in the documentation you get from
    help ic_probing_for_scheduling:probe_sched/5.
i.e. the following code (after loading lib(ic_probing_for_scheduling)):

probe_schedule(Starts,CostFun) :-
         ic:(R1::1..2), R2=2, R3=1,
         CostFun= abs(X-OldX)+abs(Y-OldY)+abs(Z-OldZ),

and run this with the query probe_schedule(S,C), and this succeeded 
without returning an error.

Could you give more details on what you did to get your error? Without 
this, it is difficult to help you; the error looks strange -- from 
looking at the code for cplex_set_obj_coeff/3 (which is implemented in 
C, and is an internal predicate used by lib(eplex)), it should only 
return the number expected error if the third argument is not a number, 
but in your error message, the third argument does look like a number -- 1.
