Perhaps you should try some spelling variations:
"coder code optimizations algorithm based" » "coder code optimization algorithm based" (Expand search), "coder code optimization algorithms based" (Expand search), "coder code optimisation algorithm based" (Expand search), "coder dose optimization algorithm based" (Expand search), "coder the optimization algorithm based" (Expand search), "coder code optimizations algorithm and" (Expand search), "code code optimizations algorithm based" (Expand search), "modern code optimizations algorithm based" (Expand search), "color code optimizations 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 code optimizations algorithm based") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder code optimizations algorithm based\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( coder code optimizations algorithm based ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder code optimizations algorithm based") OR ("_ python python python programming"))*.
