Perhaps you should try some spelling variations:
"by computation using concurrent programming" » "by computation using constraint programming" (Expand search), "by computations using concurrent programming" (Expand search), "by computation in concurrent programming" (Expand search), "by composition using concurrent programming" (Expand search), "by computation during concurrent programming" (Expand search), "by computation testing concurrent programming" (Expand search), "by computation passing concurrent programming" (Expand search), "by computational using concurrent programming" (Expand search), "of computation using concurrent programming" (Expand search), "_ computation using concurrent programming" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("by computation using concurrent programming") OR ("using using python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computation using concurrent programming\") OR (\"using using python python programming\"))".
• Removing quotes may allow a broader search: (( by computation using concurrent programming ) OR ( using using python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("by computation using concurrent programming") OR ("using using python python programming"))*.
