Hiya, I'm having trouble performing a numerical integration that involves a Minimize. I think it might have something to do with HoldAll, but am not sure how to fix it (couldn't find any actual solutions that worked in the archives). Any help most appreciated. Here is a simplified version of the code (the function and constraints I'm actually using are more complicated): ff[a_] := First[Minimize[{x + a, 0 â?¤ x â?¤ 2}, {x}]] NIntegrate[ff[a], {a, 0, 6}] Mathematica raises a Minimize::objv error, complaining that a+x contains a nonconstant expression independent of x, and so the NIntegrate fails. Ideas? Thanks, Oz
