Did you discover the same mysterious thing about the command execution time in Maple?
Here is my observation:
If I have been using this session for a long time and then if I issue a long-processing command, such as simplification of a very complicated expression, etc. After a while, Maple will get into "steady state": it keeps running and running, without consuming more memory and showing more activity, the time even counts towards 10000 second, etc.
If based on this, I think the expression is really too complicated for it to simplify, then I am wrong.
After rebooting the PC, and relaunch Maple, and start the same command to simplify the same expression, it generated a result within 15 minutes, successfully...
Why is it so strange? I cannot keep rebooting my PC, right?
