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