Perhaps you should try some spelling variations:
"_ computation using modeling problems" » "_ computations using modeling problems" (Expand search), "_ computation in modeling problems" (Expand search), "_ composition using modeling problems" (Expand search), "_ computation using modelling problems" (Expand search), "_ computation using modelling problem" (Expand search), "_ computation using modeling process" (Expand search), "_ computation using model problems" (Expand search), "_ computation using modern problems" (Expand search), "_ computation using models problems" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ computation using modeling problems") OR ("using code from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computation using modeling problems\") OR (\"using code from python programming\"))".
• Removing quotes may allow a broader search: (( _ computation using modeling problems ) OR ( using code from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computation using modeling problems") OR ("using code from python programming"))*.
