Perhaps you should try some spelling variations:
"by computation using effective program" » "by computations using effective program" (Expand search), "by computation in effective program" (Expand search), "by composition using effective program" (Expand search), "by computation using incentive program" (Expand search), "by computation using educative program" (Expand search), "by computation using selective program" (Expand search), "by computation using subjective program" (Expand search), "by computational using effective program" (Expand search), "of computation using effective program" (Expand search), "_ computation using effective program" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"by computation using effective program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( by computation using effective program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computation using effective program") OR ("using python python python programming"))*.
