Perhaps you should try some spelling variations:
"coder data optimization algorithm based" » "coder ratio optimization algorithm based" (Expand search), "coder database optimization algorithm based" (Expand search), "coder spatial optimization algorithm based" (Expand search), "cover data optimization algorithm based" (Expand search), "code data optimization algorithm based" (Expand search), "border data optimization algorithm based" (Expand search)
"in python python python programming" » "in pythons python python programming" (Expand search), "in piton python python programming" (Expand search), "in pitons python python programming" (Expand search), "_ python python python programming" (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 data optimization algorithm based") OR ("in python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder data optimization algorithm based\") OR (\"in python python python programming\"))".
• Removing quotes may allow a broader search: (( coder data optimization algorithm based ) OR ( in python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder data optimization algorithm based") OR ("in python python python programming"))*.
