Perhaps you should try some spelling variations:
"advanced computation in computer program" » "advanced computations in computer program" (Expand search), "advanced computational in computer program" (Expand search), "advance computational in computer program" (Expand search), "advanced computation and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced imputation in computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"using models systems python programming" » "using model systems python programming" (Expand search), "using model system python programming" (Expand search), "using modern systems python programming" (Expand search), "ising models systems python programming" (Expand search), "nursing models systems 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: "((\"advanced computation in computer program\") OR (\"using models systems python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation in computer program ) OR ( using models systems python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation in computer program") OR ("using models systems python programming"))*.
