Perhaps you should try some spelling variations:
"coder _ sampling algorithm based" » "coder _ mapping algorithm based" (Expand search), "coder _ matching algorithm based" (Expand search), "coder _ mapping algorithms based" (Expand search), "coder _ sampling algorithm and" (Expand search)
"via python python python programming" » "via pythons python python programming" (Expand search), "via piton python python programming" (Expand search), "via pitons python python programming" (Expand search), "in 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 _ sampling algorithm based\") OR (\"via python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ sampling algorithm based ) OR ( via python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ sampling algorithm based") OR ("via python python python programming"))*.
