Perhaps you should try some spelling variations:
"using computation passing concurrent program" » "using computation using concurrent program" (Expand search), "using computation teaching concurrent program" (Expand search), "using computation learning concurrent program" (Expand search), "using computation proving concurrent program" (Expand search), "using computation testing concurrent program" (Expand search), "using computation passing concurrent programs" (Expand search), "using computation passing concurrent programming" (Expand search), "using computational passing concurrent program" (Expand search), "using imputation passing concurrent program" (Expand search), "using compilation passing concurrent program" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: "((\"using computation passing concurrent program\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation passing concurrent program ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation passing concurrent program") OR ("using coding python python programming"))*.
