Perhaps you should try some spelling variations:
"based computational model concurrent program" » "and computational model concurrent program" (Expand search), "by computational model concurrent program" (Expand search), "based computational modeling concurrent program" (Expand search), "based computational model concurrent programs" (Expand search), "based computational model concurrent programming" (Expand search), "based computational model current program" (Expand search), "based computational power concurrent program" (Expand search), "based computational of 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.

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