Re: Request for help - Minimize

Minimize may return error (becuase constraints[i] can not be satisfied). So I want to neglect the result in this case, I don't want the program stops in this case. How can I manage it?

First, this is better written as

Table[Minimize[{objfun[i], constraints[i]}, variables], {i, 1, 100}]

but this does not filter out the cases that throw errors.

You can use check for this:

Table[
   Check[
    Minimize[{objfun[i], constraints[i]}, variables],
    "error"
   ],
  {i, 1, 100}]

If you're new to Mathematica, it is a good idea to try to avoid For[]. 
In most cases there are easier/faster alternatives.
