Perhaps you should try some spelling variations:
"based computational using subsampling program" » "and computational using subsampling program" (Expand search), "by computational using subsampling program" (Expand search), "based computation using subsampling program" (Expand search), "based computations using subsampling program" (Expand search), "based computacional usinas subsampling program" (Expand search), "based computational using sampling program" (Expand search), "based computational and subsampling program" (Expand search)
"using java on python programming" » "using java in python programming" (Expand search), "using java of python programming" (Expand search), "using java _ python programming" (Expand search), "using java and 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 subsampling program\") OR (\"using java on python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using subsampling program ) OR ( using java on python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using subsampling program") OR ("using java on python programming"))*.
