Perhaps you should try some spelling variations:
"api pythons python python programming" » "api pitons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pythons piton python programming" (Expand search), "api pythons pitons python programming" (Expand search), "api pythons pytm python programming" (Expand search), "api python python python programming" (Expand search)
"coder convex optimization algorithm in" » "closed convex optimization algorithm in" (Expand search), "or convex optimization algorithm in" (Expand search), "some convex optimization algorithm in" (Expand search), "coder convex optimization algorithm and" (Expand search), "coder convex optimization algorithm _" (Expand search), "coder convex optimization algorithm with" (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: "((\"coder convex optimization algorithm in\") OR (\"api pythons python python programming\"))~".
• Removing quotes may allow a broader search: (( coder convex optimization algorithm in ) OR ( api pythons python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder convex optimization algorithm in") OR ("api pythons python python programming"))*.
