Perhaps you should try some spelling variations:
"using optimization algorithm and array" » "time optimization algorithm and array" (Expand search), "using optimization algorithms and array" (Expand search), "using optimization algorithm based array" (Expand search), "using optimization algorithm _ array" (Expand search), "using optimization algorithm and arrays" (Expand search), "using optimization algorithm an array" (Expand search), "using optimization algorithm and arrow" (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 and array\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using optimization algorithm and array ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using optimization algorithm and array") OR ("using coding python python programming"))*.
