Hello guys,

I have a big problem with my model and get this message:

Infeasible solution. There are no superbasic variables.

How I can fix it? In the Solution report i find one equation with the status: INFES

The level is by 150. If I go under 150, I get the message and If I dont set the scalar by 151 I get the message feasible solution and then optimal solution. There are no superbasic variables.

This is the report:

The model has 39 variables and 40 constraints

with 96 Jacobian elements, 38 of which are nonlinear.

The Hessian of the Lagrangian has 19 elements on the diagonal,

0 elements below the diagonal, and 19 nonlinear variables.

** Infeasible solution. There are no superbasic variables.

CONOPT time Total 0.001 seconds

of which: Function evaluations 0.001 =100.0%

1st Derivative evaluations 0.000 = 0.0%

The equationproblem is: room…sum(j, c(j)*x(j)) =l= s;

This is the space contraint for some items without periode.

c(j) is the capacity for one item and x(j) the quantitiy of item j. s is space.

I hope anyone can help me.

regards,
