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 fusing python python programming" » "using using python python programming" (Expand search), "using fusing pythons python programming" (Expand search), "using fusing piton python programming" (Expand search), "using fusing pitons python programming" (Expand search), "using nursing python python programming" (Expand search), "using fusions python python programming" (Expand search), "using fusion 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: (("based computation using clustering problem") OR ("using fusing python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using clustering problem\") OR (\"using fusing python python programming\"))".
• Removing quotes may allow a broader search: (( based computation using clustering problem ) OR ( using fusing python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation using clustering problem") OR ("using fusing python python programming"))*.
