Perhaps you should try some spelling variations:
"using computational in complex program" » "and computational in complex program" (Expand search), "using computational and complex program" (Expand search), "using computational _ complex program" (Expand search), "using computational 3d complex program" (Expand search), "using computational in simplex program" (Expand search), "using computational in complex programmes" (Expand search), "using computational in complex prograded" (Expand search)
"using model python python programming" » "using model pythons python programming" (Expand search), "using model piton python programming" (Expand search), "using model pitons python programming" (Expand search), "using modulo python python programming" (Expand search), "using monty python python programming" (Expand search), "using tool python python programming" (Expand search), "ising model python python programming" (Expand search), "using modis python python programming" (Expand search), "using mobile 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 in complex program\") OR (\"using model python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational in complex program ) OR ( using model python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational in complex program") OR ("using model python python programming"))*.
