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 computational using subsampling program\") OR (\"using of python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational using subsampling program ) OR ( using of python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational using subsampling program") OR ("using of python python programming"))*.
