Fitness problem for weights

[snan...@shilpasys.com]

TypeError: Both weights and assigned values must be a sequence of numbers when assigning to values of <class 'deap.creator.FitnessMax'>. Currently assigning value(s) 55.121628595728602 of <class 'numpy.float64'> to a fitness with weights (-1.0,).

[François-Michel De Rainville]

The value returned by your evaluation function must be sequence, e.g. a tuple. Note the trailing comma

return 55.12, 

Cheers,
