Perhaps you should try some spelling variations:
"_ computation using modelling problem" » "_ computations using modelling problem" (Expand search), "_ computation in modelling problem" (Expand search), "_ composition using modelling problem" (Expand search), "_ computation using modelling problems" (Expand search), "_ computation using modeling problems" (Expand search), "_ computation using covering problem" (Expand search), "_ computation using modeling problem" (Expand search), "_ computation business 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: "((\"_ computation using modelling problem\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( _ computation using modelling problem ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computation using modelling problem") OR ("using code from python programming"))*.
