hi, 2 questions,
1. when I tried to use to solve Mix Integer linear program,
for each integer variables, It will warn as follows
"Eplex warning: Imposing integer bounds on variable(s) _15437 for eplex
instance eplex does not impose integer type"
Is there any ways to stop or ignore this type of warnings ?

2. As I put constraints using Big-M method for each pair of disjunctive
constraints,
with more and more constraints, the following errors will occur many times.
"Clp6002E 1 bad bound pairs or bad objectives were found - first at C98"
Although at the end, I still got an answer from eplex.
But will these errors make the result solved by eplex incorrect ?
Or not a optimal solution ?

thanks
