I might be doing something wrong but, say I have the following problem:

minimize v = 0.1a + .15b subject to
207a + 173b  >= 2000000
86b >= 500000

It correctly solves the problem with solutions a=4802.831142568 and b=5813.953488372001

However, when applying integer constraints to a and b, it gives an error saying No solution with the desired integer values exists . When i know the integer solutions are a=4803 and b=5814 from solving it by hand.

Problem that gives the error:

minimize v = 0.1a + .15b subject to
207a + 173b  >= 2000000
86b >= 500000
integer a, b

Need anything else let me know,
Thanks
