testing accuracy on nonlinear systems

mdb ยท Tue Jun 24, 2014 2:50 pm

Do anyone know of a way to compare the accuracy of two different algorithms which solve nonlinear systems of equations? Specifically, square systems of homogeneous degree two.

More specifically, suppose we solve 1000 different systems of nonlinear equations using one algorithm and another algorithm (on the same 1000 systems). Without knowing the exact solutions is there a way to determine which one is more accurate?
