Perhaps you should try some spelling variations:
"exploring computation using computer program" » "exploring computational using computer program" (Expand search), "exploring communication using computer program" (Expand search), "employing computational using computer program" (Expand search), "exploring computations using computer program" (Expand search), "exploring computation in computer program" (Expand search), "exploring composition using 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: "((\"exploring computation using computer program\") OR (\"using model lambda python programming\"))~".
• Removing quotes may allow a broader search: (( exploring computation using computer program ) OR ( using model lambda python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("exploring computation using computer program") OR ("using model lambda python programming"))*.
