Perhaps you should try some spelling variations:
"cover modelling using diffusing computation" » "cover modeling using diffusing computation" (Expand search), "novel modelling using diffusing computation" (Expand search), "river modelling using diffusing computation" (Expand search), "cover modelling using diffusion computation" (Expand search), "cover modelling using diffusive computation" (Expand search), "cover modelling using defocusing computation" (Expand search)
"_ python python python programming" » "_ pythons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ pitons 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: "((\"cover modelling using diffusing computation\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( cover modelling using diffusing computation ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("cover modelling using diffusing computation") OR ("_ python python python programming"))*.
