Perhaps you should try some spelling variations:
"code single objective algorithms parallel" » "code single detection algorithms parallel" (Expand search), "code single adaptive algorithms parallel" (Expand search), "code single selection algorithms parallel" (Expand search), "code single objective algorithmes parallele" (Expand search), "code single objective algorithmes paralleles" (Expand search), "code single objective algorithms parameters" (Expand search), "mode single objective algorithms parallel" (Expand search), "one single objective algorithms parallel" (Expand search), "wide single objective algorithms parallel" (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: (("code single objective algorithms parallel") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code single objective algorithms parallel\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( code single objective algorithms parallel ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("code single objective algorithms parallel") OR ("_ python python python programming"))*.
