Perhaps you should try some spelling variations:
"developing computation using computer program" » "developing computational using computer program" (Expand search), "developing population using computer program" (Expand search), "developing communication using computer program" (Expand search), "developing computations using computer program" (Expand search), "developing computation in computer program" (Expand search), "developing composition using computer program" (Expand search)
"using model in python programming" » "ising model in python programming" (Expand search), "using modis in python programming" (Expand search), "using mobile in python programming" (Expand search), "using model _ 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: "((\"developing computation using computer program\") OR (\"using model in python programming\"))~".
• Removing quotes may allow a broader search: (( developing computation using computer program ) OR ( using model in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("developing computation using computer program") OR ("using model in python programming"))*.
