Perhaps you should try some spelling variations:
"developing computational using computer program" » "applying computational using computer program" (Expand search), "teaching computational using computer program" (Expand search), "learning computational using computer program" (Expand search), "developing computation using computer program" (Expand search), "developing computations using computer program" (Expand search), "developing computacional usinas computer program" (Expand search)
"using model and python programming" » "ising model and python programming" (Expand search), "using modis and python programming" (Expand search), "using mobile and python programming" (Expand search), "using model in python programming" (Expand search), "using model on python programming" (Expand search), "using model api python programming" (Expand search), "using modeling and 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 computational using computer program\") OR (\"using model and python programming\"))~".
• Removing quotes may allow a broader search: (( developing computational using computer program ) OR ( using model and python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("developing computational using computer program") OR ("using model and python programming"))*.
