Perhaps you should try some spelling variations:
"using optimization algorithm gate array" » "time optimization algorithm gate array" (Expand search), "using optimization algorithm state array" (Expand search), "using optimization algorithm ga array" (Expand search), "using optimization algorithm case array" (Expand search), "using optimization algorithm gate arrays" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking python 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: "((\"using optimization algorithm gate array\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using optimization algorithm gate array ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using optimization algorithm gate array") OR ("using coding python python programming"))*.
