Thank you very much for your answers.
I don't understand how parameters in the field "Maxima command" and automatic creation of the optimized image are related. If I don't click the button "Create Maxima image", the parameter in the field "Maxima command" doesn't work? It doesn't affect anything?
I read in the documentation
that the Maxima's timeout should be longer than the CAS connection timeout. Why is this times equal when automatically creating an optimized image? Both are equal to 10 seconds. Can I write "timeout --kill-after=15s 15s maxima" in the field "Maxima command"?
One more question. Do I understand correctly that creating Maxima image is done by compiling it from sources using gcc?
