Perhaps you should try some spelling variations:
"and computational sparse coding program" » "and computational parser coding program" (Expand search), "and computation sparse coding program" (Expand search), "and computational search coding program" (Expand search), "_ computational sparse coding program" (Expand search), "and computational sparse cloning program" (Expand search), "and computational sparse loading program" (Expand search), "and computational sparse cooling programs" (Expand search)
"by computational code computer program" » "by computational model computer program" (Expand search), "by computational cost computer program" (Expand search), "by computational models computer program" (Expand search), "_ computational code computer program" (Expand search), "by computational node computer program" (Expand search), "by computational one computer program" (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: (("by computational code computer program") OR ("and computational sparse coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational code computer program\") OR (\"and computational sparse coding program\"))".
• Removing quotes may allow a broader search: (( by computational code computer program ) OR ( and computational sparse coding program )).
• Adding a wildcard symbol may retrieve word variants: (("by computational code computer program") OR ("and computational sparse coding program"))*.
