Perhaps you should try some spelling variations:
"the computational using allocation problem" » "the computation using allocation problem" (Expand search), "the computations using allocation problem" (Expand search), "the computacional usinas allocation problem" (Expand search), "the computational using location problem" (Expand search), "_ computational using allocation problem" (Expand search), "and computational using allocation problem" (Expand search), "the computational using association problem" (Expand search), "the computational single allocation 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: "((\"the computational using allocation problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( the computational using allocation problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("the computational using allocation problem") OR ("using coding python python programming"))*.
