Perhaps you should try some spelling variations:
"by computation in loading problem" » "by computation in routing problem" (Expand search), "by computation in planning problem" (Expand search), "by computational in loading problem" (Expand search), "of computation in loading problem" (Expand search), "_ computation in loading problem" (Expand search), "by computation and loading problem" (Expand search), "by computation of loading problem" (Expand search), "by imputation in loading problem" (Expand search), "by computation in leading problem" (Expand search), "by computation ii loading problem" (Expand search), "by computation i loading problem" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using 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 computation in loading problem\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( by computation in loading problem ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computation in loading problem") OR ("using using python python programming"))*.
