Perhaps you should try some spelling variations:
"_ computation using concurrent program" » "_ computation using concurrent programs" (Expand search), "_ computation using concurrent programming" (Expand search), "_ computations using concurrent program" (Expand search), "_ computation in concurrent program" (Expand search), "_ composition using concurrent program" (Expand search), "_ computation during concurrent program" (Expand search), "_ computation testing concurrent program" (Expand search), "_ computation passing concurrent 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: "((\"_ computation using concurrent program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( _ computation using concurrent program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computation using concurrent program") OR ("using python python python programming"))*.
