Perhaps you should try some spelling variations:
"based computational coder allocation problem" » "and computational coder allocation problem" (Expand search), "by computational coder allocation problem" (Expand search), "based computational code allocation problem" (Expand search), "based computational codes allocation problem" (Expand search), "based computational model allocation problem" (Expand search), "based computational coder location problem" (Expand search), "based computational power allocation problem" (Expand search), "based computational order allocation problem" (Expand search), "based computational over allocation problem" (Expand search)
"using social python python programming" » "using scilab python python programming" (Expand search), "using social pythons python programming" (Expand search), "using social piton python programming" (Expand search), "using social pitons python programming" (Expand search), "dumping social python python programming" (Expand search), "using solid 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 coder allocation problem\") OR (\"using social python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational coder allocation problem ) OR ( using social python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational coder allocation problem") OR ("using social python python programming"))*.
