Perhaps you should try some spelling variations:
"based computation using declarative programming" » "based computation using reactive programming" (Expand search), "based computational using declarative programming" (Expand search), "based competition using declarative programming" (Expand search), "based compilation using declarative programming" (Expand search), "based computations using declarative programming" (Expand search), "based computation in declarative programming" (Expand search), "based composition using declarative programming" (Expand search), "based computation mining declarative programming" (Expand search), "based computation engine declarative programming" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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 computation using declarative programming\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using declarative programming ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using declarative programming") OR ("using in python python programming"))*.
