Perhaps you should try some spelling variations:
"and computation using declarative programming" » "and computation using reactive programming" (Expand search), "and computations using declarative programming" (Expand search), "and computation in declarative programming" (Expand search), "and composition using declarative programming" (Expand search), "and computation mining declarative programming" (Expand search), "and computation engine declarative programming" (Expand search), "and computational using declarative programming" (Expand search), "of computation using declarative programming" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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: "((\"and computation using declarative programming\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using declarative programming ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using declarative programming") OR ("using code from python programming"))*.
