Perhaps you should try some spelling variations:
"based computation using completion problems" » "based computation using completion problem" (Expand search), "based computation using complex problems" (Expand search), "based computation using conduction problems" (Expand search), "based computational using completion problems" (Expand search), "based competition using completion problems" (Expand search), "based compilation using completion problems" (Expand search), "based computations using completion problems" (Expand search), "based computation in completion problems" (Expand search), "based composition using completion problems" (Expand search), "based computation using compilation problems" (Expand search), "based computation using compression problems" (Expand search), "based computation using complete problems" (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: "((\"based computation using completion problems\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using completion problems ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using completion problems") OR ("using codigo python python programming"))*.
