Perhaps you should try some spelling variations:
"coder using optimization algorithm modeling" » "coder time optimization algorithm modeling" (Expand search), "coder using optimization algorithm considering" (Expand search), "coders using optimization algorithm modeling" (Expand search), "cover using optimization algorithm modeling" (Expand search), "code using optimization algorithm modeling" (Expand search)
"_ pythons python python programming" » "_ pitons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ pythons piton python programming" (Expand search), "_ pythons pitons python programming" (Expand search), "_ pythons pytm python programming" (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: "((\"coder using optimization algorithm modeling\") OR (\"_ pythons python python programming\"))~".
• Removing quotes may allow a broader search: (( coder using optimization algorithm modeling ) OR ( _ pythons python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder using optimization algorithm modeling") OR ("_ pythons python python programming"))*.
