Perhaps you should try some spelling variations:
"and computations in complex program" » "and computation in complex program" (Expand search), "and computational in complex program" (Expand search), "and competitions in complex program" (Expand search), "and computation of complex program" (Expand search), "and computation and complex program" (Expand search), "and computations in simplex program" (Expand search), "and computations in complex programmes" (Expand search), "and computations in complex prograded" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"and computations in complex program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computations in complex program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computations in complex program") OR ("using python python python programming"))*.
