Perhaps you should try some spelling variations:
"advanced computations using computer program" » "advanced computational using computer program" (Expand search), "advance computational using computer program" (Expand search), "advanced communications using computer program" (Expand search), "advanced computation using computer program" (Expand search), "advanced populations using computer program" (Expand search), "advanced computations in computer program" (Expand search)
"using model lambda python programming" » "using modelo lambda python programming" (Expand search), "using model land python programming" (Expand search), "using modelo lambdacdm python programming" (Expand search), "ising model lambda python programming" (Expand search), "using modis lambda python programming" (Expand search), "using mobile lambda 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 computations using computer program\") OR (\"using model lambda python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computations using computer program ) OR ( using model lambda python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations using computer program") OR ("using model lambda python programming"))*.
