Perhaps you should try some spelling variations:
"based computational and clustering problem" » "and computational and clustering problem" (Expand search), "by computational and clustering problem" (Expand search), "based computational and covering problem" (Expand search), "based computational fluid clustering problem" (Expand search), "based computational data clustering problem" (Expand search), "based computational _ clustering problem" (Expand search)
"using api python python programming" » "using api pythons python programming" (Expand search), "using api piton python programming" (Expand search), "using api pitons python programming" (Expand search), "using rpa python python programming" (Expand search), "using manim python python programming" (Expand search), "using ai python python programming" (Expand search), "using ape python python programming" (Expand search), "using app 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: "((\"based computational and clustering problem\") OR (\"using api python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational and clustering problem ) OR ( using api python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational and clustering problem") OR ("using api python python programming"))*.
