Dear all,
I am a newbie in this tool and I would like to ask a simple doubt.
I have seen (and tested) that the example sample.c it is not possible to
set a coefficient to zero at the table ar[x]=0.0
This is also highlighted on the documentation.
But I was wondering how I could express a restriction like this
R >= x1+x2+x3
x1 <= g1
x2 <= g2
x3 <= g3
i have expressed the problem like
r = x1+x2+x3 (1)
x1 = p (2)
x2 = q (3)
x3 = 3 (4)
However it implies, for example in the second equation, that x2 and x3
coefficient are zero.
By using files (i.e. format cplexlp) is easy to express these
restrictions but I would be interested in using the API C.
Thanks in advance.
