Perhaps you should try some spelling variations:
"and computations using copositive programming" » "and computations using objective programming" (Expand search), "and computation using copositive programming" (Expand search), "and populations using copositive programming" (Expand search), "and computations in copositive programming" (Expand search), "and computational using copositive programming" (Expand search), "and competitions using copositive programming" (Expand search), "and computations using positive programming" (Expand search), "and computations using competitive programming" (Expand search), "and computations using composite 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: "((\"and computations using copositive programming\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( and computations using copositive programming ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computations using copositive programming") OR ("using codigo python python programming"))*.
