Perhaps you should try some spelling variations:
"based computation using diffusion program" » "based computational using diffusion program" (Expand search), "based competition using diffusion program" (Expand search), "based compilation using diffusion program" (Expand search), "based computations using diffusion program" (Expand search), "based computation in diffusion program" (Expand search), "based composition using diffusion program" (Expand search), "based computation using diffusion problem" (Expand search), "based computation using diffusion problems" (Expand search), "based computation using diffusion process" (Expand search)
"using total python python programming" » "using total pythons python programming" (Expand search), "using total piton python programming" (Expand search), "using total pitons python programming" (Expand search), "using tool 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: "((\"based computation using diffusion program\") OR (\"using total python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using diffusion program ) OR ( using total python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using diffusion program") OR ("using total python python programming"))*.
