Perhaps you should try some spelling variations:
"by computational models concurrent programming" » "by computational models constraint programming" (Expand search), "by computational model concurrent programming" (Expand search), "by computational modeling concurrent programming" (Expand search), "by computational modelling concurrent programming" (Expand search), "by computational models current programming" (Expand search), "by computational modelos concorrentes programming" (Expand search), "by computational model current programming" (Expand search), "_ computational models concurrent programming" (Expand search), "and computational models concurrent programming" (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: "((\"by computational models concurrent programming\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational models concurrent programming ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational models concurrent programming") OR ("using coding python python programming"))*.
