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