Perhaps you should try some spelling variations:
"using computational methods array program" » "using computational model array program" (Expand search), "and computational methods array program" (Expand search), "using computational methods areas program" (Expand search), "using computational methods leray program" (Expand search), "using computational methods are program" (Expand search), "using computational methods spray program" (Expand search), "using computational methods ray program" (Expand search), "using computational methods warranty program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: "((\"using computational methods array program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational methods array program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational methods array program") OR ("using in python python programming"))*.
