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 by ddr program" » "code solution by ddr program" (Expand search), "copper solution by ddr program" (Expand search), "powder solution by ddr program" (Expand search), "coder solutions by ddr program" (Expand search), "coder solution _ ddr program" (Expand search), "coder solution blow ddr program" (Expand search), "coder solution by r program" (Expand search), "coder solution by mar program" (Expand search), "coder solution by ladder program" (Expand search), "coder solution by ddrt program" (Expand search), "coder solution by dda program" (Expand search), "coder solution by ddt 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: "((\"coder solution by ddr program\") OR (\"based optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution by ddr program ) OR ( based optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution by ddr program") OR ("based optimization python python programming"))*.
