Perhaps you should try some spelling variations:
"coder coder propagation algorithm problem" » "coder coder approximation algorithm problem" (Expand search), "coder coder approximation algorithms problem" (Expand search), "coder mode propagation algorithm problem" (Expand search), "coder model propagation algorithm problem" (Expand search), "coder modes propagation algorithm problem" (Expand search), "coder coder propagation algorithms problem" (Expand search), "coder coder propagation algoritmo problema" (Expand search), "coder coder propagation logarithm problem" (Expand search), "coder decoder propagation algorithm problem" (Expand search), "code code propagation algorithm problem" (Expand search), "decoder codec propagation algorithm problem" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api 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 coder propagation algorithm problem") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder propagation algorithm problem\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder coder propagation algorithm problem ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coder propagation algorithm problem") OR ("api python python python programming"))*.
