From the reference
J.J. More, B.S. Garbow and K.E. Hillstrom, "Testing Unconstrained Optimization Software"
problem 26 seems to be defined with a slight sign difference
riel = n + iel ( 1 - ciel ) - siel;
instead of
riel = n - iel ( 1 - ciel ) - siel;
Which is intended? Note that this does not change the global minimizers or lower bound of f=0.
Many thanks for releasing OPM, I am finding it helpful for checking code.
