Perhaps you should try some spelling variations:
"based computation using clustering problem" » "based computation using covering problem" (Expand search), "based computational using clustering problem" (Expand search), "based competition using clustering problem" (Expand search), "based compilation using clustering problem" (Expand search), "based computations using clustering problem" (Expand search), "based computation in clustering problem" (Expand search), "based composition using clustering problem" (Expand search), "based computation and clustering problem" (Expand search), "based computation means clustering problem" (Expand search)
"using codes from python programming" » "using code from python programming" (Expand search), "using anodes from python programming" (Expand search), "using cone from python programming" (Expand search), "using codes from pathogen programming" (Expand search), "using codes from anthony programming" (Expand search), "using cestodes from 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: "((\"based computation using clustering problem\") OR (\"using codes from python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using clustering problem ) OR ( using codes from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using clustering problem") OR ("using codes from python programming"))*.
