Perhaps you should try some spelling variations:
"based computational workflow matching problem" » "based communicational workflow matching problem" (Expand search), "and computational workflow matching problem" (Expand search), "by computational workflow matching problem" (Expand search), "based computational workflow mapping problem" (Expand search), "based computational workflow capturing problem" (Expand search), "based computational flow matching problem" (Expand search), "based computational workflow packing problem" (Expand search), "based computational workflow teaching problem" (Expand search), "based computational workflow cutting problem" (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: "((\"based computational workflow matching problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational workflow matching problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational workflow matching problem") OR ("using coding python python programming"))*.
