Perhaps you should try some spelling variations:
"by computation using sampling program" » "by computations using sampling program" (Expand search), "by computation in sampling program" (Expand search), "by composition using sampling program" (Expand search), "by computation using labeling program" (Expand search), "by computation using smoking program" (Expand search), "by computation using jumping program" (Expand search), "by computational using sampling program" (Expand search), "of computation using sampling program" (Expand search), "_ computation using sampling program" (Expand search), "by computation using subsampling program" (Expand search), "by computation using saline program" (Expand search), "by computation using samples program" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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: "((\"by computation using sampling program\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( by computation using sampling program ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computation using sampling program") OR ("using code from python programming"))*.
