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 ptr1 python programming" » "ising models ptr1 python programming" (Expand search), "using model ptr1 python programming" (Expand search), "nursing models ptr1 python programming" (Expand search), "using models petri python programming" (Expand search), "using models part python programming" (Expand search), "using models pwr python programming" (Expand search), "using models piton 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 ptr1 python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using computer program ) OR ( using models ptr1 python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using computer program") OR ("using models ptr1 python programming"))*.
