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 modes from python programming" » "using models from python programming" (Expand search), "using modis from python programming" (Expand search), "using model from python programming" (Expand search), "using modes from pathogen programming" (Expand search), "using modes from anthony programming" (Expand search), "using codes from 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 modes from python programming\"))~".
• Removing quotes may allow a broader search: (( developing computation using computer program ) OR ( using modes from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("developing computation using computer program") OR ("using modes from python programming"))*.
