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