SLSQP - Inequality constraints incompatible

[Rakesh Kumar]

I am solving the problem described in Section II - A of this paper: https://pdfs.semanticscholar.org/9809/baec1b0881a0e7890bbb75819f2f40906f94.pdf

Essentially the problem has equality constraints, thus it seems like SLSQP is the only way to go. I am using SciPy 0.19.0 on Ubuntu.

For small graphs, the solution is produced, however for larger graphs, with even up to 10 nodes, the I get the error "Inequality constraints incompatible". While there are bounds on each variable to have a positive value, but no inequality constraints. So, I am not sure what is causing this.

The code to reproduce this is available at: https://github.com/gopchandani/ddos_model/blob/master/src/flow_solvers/sor.py

If you'd like to run and reproduce with a dummy topology, kindly use the file src/model/simple_model.py

Any help would be appreciated!

I also searched around for the same problem but could not find anything helpful. Did you come up with any breakthrough?

Hi,

I am facing a similar issue. Have you resolved this issue for your case?
