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 code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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 code from python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in modelling problem ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in modelling problem") OR ("using code from python programming"))*.
