Perhaps you should try some spelling variations:
"using computational python computer program" » "using computacional python computer program" (Expand search), "using computacional vpython computer program" (Expand search), "using computacionais python computer program" (Expand search), "and computational python computer program" (Expand search)
"based computational sparse coding program" » "based computational parser coding program" (Expand search), "based computation sparse coding program" (Expand search), "based computational search coding program" (Expand search), "and computational sparse coding program" (Expand search), "by computational sparse coding program" (Expand search), "based computational sparse cloning program" (Expand search), "based computational sparse loading program" (Expand search), "based computational sparse cooling programs" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computational sparse coding program") OR ("using computational python computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational sparse coding program\") OR (\"using computational python computer program\"))*".
• Removing quotes may allow a broader search: (( based computational sparse coding program ) OR ( using computational python computer program ))*.
