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)
"coder solution laser coding program" » "code solution laser coding program" (Expand search), "powder solution laser coding program" (Expand search), "copper solution laser coding program" (Expand search), "coder resolution laser coding program" (Expand search), "coder solution based coding program" (Expand search), "coder solution base coding program" (Expand search), "coder solution laser cloning program" (Expand search), "coder solution laser loading program" (Expand search), "coder solution laser cooling programs" (Expand search), "coder solution laser cooling program" (Expand search), "coder solution laser coating program" (Expand search), "coder solution paper coding program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder solution laser coding program") OR ("and optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder solution laser coding program\") OR (\"and optimization python python programming\"))".
• Removing quotes may allow a broader search: (( coder solution laser coding program ) OR ( and optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder solution laser coding program") OR ("and optimization python python programming"))*.
