Perhaps you should try some spelling variations:
"based computational using sampling program" » "and computational using sampling program" (Expand search), "by computational using sampling program" (Expand search), "based computation using sampling program" (Expand search), "based computations using sampling program" (Expand search), "based computacional usinas sampling program" (Expand search), "based computational using labeling program" (Expand search), "based computational using smoking program" (Expand search), "based computational using jumping program" (Expand search), "based computational using subsampling program" (Expand search), "based computational using saline program" (Expand search), "based computational using samples program" (Expand search)
"using mcnp python python programming" » "using mcnp pythons python programming" (Expand search), "using mcnp piton python programming" (Expand search), "using mcnp pitons python programming" (Expand search), "using msn python python programming" (Expand search), "using monty python python programming" (Expand search), "using manim python python programming" (Expand search), "using mcnp5 python python programming" (Expand search), "using icnp python python programming" (Expand search), "using map python 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: "((\"based computational using sampling program\") OR (\"using mcnp python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using sampling program ) OR ( using mcnp python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using sampling program") OR ("using mcnp python python programming"))*.
