Perhaps you should try some spelling variations:
"based computation using complexity from" » "based computational using complexity from" (Expand search), "based competition using complexity from" (Expand search), "based compilation using complexity from" (Expand search), "based computations using complexity from" (Expand search), "based computation in complexity from" (Expand search), "based composition using complexity from" (Expand search), "based computation using complex from" (Expand search), "based computation using complete from" (Expand search), "based computation design complexity from" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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 complexity from\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using complexity from ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using complexity from") OR ("using code from python programming"))*.
