Perhaps you should try some spelling variations:
"coder decoder tree algorithm parallelization" » "coder decoder tree automatic parallelization" (Expand search), "coder decoder tree algorithms parallelization" (Expand search), "coder decoder the algorithm parallelization" (Expand search), "coder decoder greedy algorithm parallelization" (Expand search), "encoder decoder tree algorithm parallelization" (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 decoder tree algorithm parallelization") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder decoder tree algorithm parallelization\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( coder decoder tree algorithm parallelization ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder decoder tree algorithm parallelization") OR ("_ python python python programming"))*.
