Perhaps you should try some spelling variations:
"advanced calculation in computational program" » "advanced glycation in computational program" (Expand search), "advanced calculation and computational program" (Expand search), "advanced calculation _ computational program" (Expand search), "advanced calculation of computational program" (Expand search), "advanced calculations and computational program" (Expand search)
"advanced encryption in computer program" » "advanced encryption and computer program" (Expand search), "advanced encryption of computer program" (Expand search), "advanced description in computer program" (Expand search), "advanced encryption _ computer program" (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: "((\"advanced encryption in computer program\") OR (\"advanced calculation in computational program\"))~".
• Removing quotes may allow a broader search: (( advanced encryption in computer program ) OR ( advanced calculation in computational program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced encryption in computer program") OR ("advanced calculation in computational program"))*.
