Perhaps you should try some spelling variations:
integer programming » linear programming (Expand search)
decrease integer » decrease catheter (Expand search), decrease after (Expand search), decrease income (Expand search)
problem python » problem method (Expand search)
based problem » based problems (Expand search), based probe (Expand search), posed problem (Expand search)
python based » action based (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease _ decrease integer programming ) OR ( python based problem python programming ))~.
