Perhaps you should try some spelling variations:
"based optimization python python programming" » "based optimization method python programming" (Expand search), "based optimization option python programming" (Expand search), "based optimization methods python programming" (Expand search), "and optimization python python programming" (Expand search), "based optimization pythons python programming" (Expand search), "based optimization piton python programming" (Expand search), "based optimization pitons python programming" (Expand search)
"coder solution in example problem" » "coder solution in sample problem" (Expand search), "coder solution in sample problems" (Expand search), "code solution in example problem" (Expand search), "copper solution in example problem" (Expand search), "powder solution in example problem" (Expand search), "coder solutions in example problem" (Expand search), "coder solution and example problem" (Expand search), "coder solution _ example problem" (Expand search), "coder solution an example problem" (Expand search), "coder solution on example problem" (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 solution in example problem\") OR (\"based optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution in example problem ) OR ( based optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution in example problem") OR ("based optimization python python programming"))*.
