sargan fmin problem

[sametcopur]

i might be using test functions in incorrect way, but in Sargan problem

{'name': 'Sargan', 'dim': 5, 'int': None, 'res': None},

wtih this setup problem bounds are [(-2, 4), (-2, 4), (-2, 4), (-2, 4), (-2, 4)]

and

with this solution array([-2., 4., -2., 4., -2.]) i can get -100.0 in objective, but function fmin says 0.
