Pyomo + CBC

[Optimization team]

Dear Pyomo Experts, 

I have two questions :

1- Is there any options for cbc solver to stop when a feasible solution is found? 

I knwo there is a opt.options['seconds'] =100 but when I specify small numbers it does not find a feasible one 

2- Is there any list for CBC options ? so I can read them all

Best regards

You can get a list of CBC options by:

- Open a CMD or PowerQuery window

- Start CBC by typing: CBC

- To make the output more verbose, type: verbose 15

- To get a list of parameters, type: ?

To stop when you have a feasible solution, you could try the following options in various combinations: allowableGap, ratioGap, presolve, maxIterations. Alternatively, you could constrain the objective function value, via trial-and-error, to find the point where the model becomes feasible.
