Perhaps you should try some spelling variations:
"and computation using integral programming" » "and computation using interval programming" (Expand search), "and computation using integrated programming" (Expand search), "and computation using integer programming" (Expand search), "and computations using integral programming" (Expand search), "and computation in integral programming" (Expand search), "and composition using integral programming" (Expand search), "and computational using integral programming" (Expand search), "of computation using integral programming" (Expand search), "and computation using internal programming" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"and computation using integral programming\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using integral programming ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using integral programming") OR ("using python python python programming"))*.
