Hi all, I am trying to use the interface to use the Mixed Integer Programming features in Sage. One of the things I would like to do is to limit the execution time to a certain number of seconds and return the current best valid solution.
When trying to follow the instructions here: http://www.sagemath.org/doc/reference/numerical/sage/numerical/backends/glpk_backend.html#sage.numerical.backends.glpk_backend.GLPKBackend.solver_parameter I run into problems. When setting the timelimit parameter to 10 seconds for example and checking the value of the parameter afterwards, I can see it has been updated, but the program execution ignores the setting and just keeps running for a long time. I tried setting instead to set the timelimit_intopt parameter to 10000, but when I do this, I get "ValueError: This parameter is not available." I went to the code to check I was using the correct string and I see nothing wrong. Can someone point me in the right direction? I am using Sage 6.1.1 on Ubuntu 64 bits.
