Perhaps you should try some spelling variations:
"and optimization python python programming" » "and optimization method python programming" (Expand search), "and optimization option python programming" (Expand search), "and optimization methods python programming" (Expand search), "and optimization pythons python programming" (Expand search), "and optimization piton python programming" (Expand search), "and optimization pitons python programming" (Expand search)
"collisions using in coding program" » "collisions with in coding program" (Expand search), "collisions using in cloning program" (Expand search), "collisions using in loading program" (Expand search), "collisions using in cooling programs" (Expand search), "collisions using on coding program" (Expand search), "collisions using in decoding program" (Expand search), "collisions using non coding program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"collisions using in coding program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( collisions using in coding program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("collisions using in coding program") OR ("and optimization python python programming"))*.
