Perhaps you should try some spelling variations:
"advanced computation using diffusion problem" » "advanced computations using diffusion problem" (Expand search), "advanced computational using diffusion problem" (Expand search), "advance computational using diffusion problem" (Expand search), "advanced computation in diffusion problem" (Expand search), "advanced composition using diffusion problem" (Expand search), "advanced computation using diffusion process" (Expand search)
"using modeling api python programming" » "using model api python programming" (Expand search), "using modern api python programming" (Expand search), "using models api python programming" (Expand search), "using modeling rapid python programming" (Expand search), "using modeling anti python programming" (Expand search), "using modeling amps python programming" (Expand search), "using modeling rpa python programming" (Expand search), "using modeling manim 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: "((\"advanced computation using diffusion problem\") OR (\"using modeling api python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using diffusion problem ) OR ( using modeling api python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using diffusion problem") OR ("using modeling api python programming"))*.
