Perhaps you should try some spelling variations:
"coder coder on convex programming" » "coder coder on cone programming" (Expand search), "coder coder on computer programming" (Expand search), "coder decoder on convex programming" (Expand search), "code code on convex programming" (Expand search), "decoder codec on convex programming" (Expand search), "coder coder non convex programming" (Expand search), "coder coder of convex programming" (Expand search), "coder coder in convex programming" (Expand search), "coder code on convex programming" (Expand search), "coder codes on convex programming" (Expand search), "coder powder on convex programming" (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder on convex programming\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder on convex programming ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder on convex programming") OR ("in python python python programming"))*.
