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