Find out if LinearProgramming has found a solution

Hello,

the subject says it: I would like to find out whether
LinearProgramming has found a solution or not. Currently, I do


result = LinearProgramming[costs, incidenceMatrix, rhs, capacities];
If[NumberQ[First[result]],...]


which works, but I guess there is a more elegant way to do it.

Any hint appreciated,

Karsten.
