Perhaps you should try some spelling variations:
"based computation using relative error" » "based computational using relative error" (Expand search), "based competition using relative error" (Expand search), "based compilation using relative error" (Expand search), "based computations using relative error" (Expand search), "based computation in relative error" (Expand search), "based composition using relative error" (Expand search), "based computation using native error" (Expand search), "based computation using generative error" (Expand search), "based computation using refractive error" (Expand search), "based computation using refractive errors" (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 relative error\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using relative error ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using relative error") OR ("using codigo python python programming"))*.
