Perhaps you should try some spelling variations:
"based computation using activity program" » "based computational using activity program" (Expand search), "based competition using activity program" (Expand search), "based compilation using activity program" (Expand search), "based computations using activity program" (Expand search), "based computation in activity program" (Expand search), "based composition using activity program" (Expand search), "based computation fishing activity program" (Expand search), "based computation guiding activity program" (Expand search), "based computation mining activity program" (Expand search)
"using models python python programming" » "using modulo python python programming" (Expand search), "using modeling vpython python programming" (Expand search), "using models pythons python programming" (Expand search), "using models piton python programming" (Expand search), "using models pitons python programming" (Expand search), "ising models python python programming" (Expand search), "using model python python programming" (Expand search), "nursing models 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 activity program\") OR (\"using models python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using activity program ) OR ( using models python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using activity program") OR ("using models python python programming"))*.
