[Help-glpk] Minimizing an array sum

[Edilson Vasconcelos de Melo Junior]

Hi,

I'm using GLPK C API and I'm having problems to express my objective.

I have about 40 conditions: a*year[i] + b*measure[i] + c + d[i] = res[i]

I have to find the tuple {a,b,c}, where sum{d[i]} in minimum

Data I have: arrays year[], measurem[], res[]. This is NOT LPI

Any ideas?

Thanks,

Dirso
