Perhaps you should try some spelling variations:
"using computation in modelling problem" » "using computational in modelling problem" (Expand search), "using imputation in modelling problem" (Expand search), "using compilation in modelling problem" (Expand search), "using computation in modelling problems" (Expand search), "using computation in modeling problems" (Expand search), "using computation in covering problem" (Expand search), "using computation and modelling problem" (Expand search), "using computation of modelling problem" (Expand search), "using computation in modeling problem" (Expand search), "using computation 3d modelling 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: "((\"using computation in modelling problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in modelling problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in modelling problem") OR ("using coding python python programming"))*.
