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