Perhaps you should try some spelling variations:
"advanced computation and computer program" » "advanced computations and computer program" (Expand search), "advanced computational and computer program" (Expand search), "advance computational and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"dft calculation of computing program" » "dft calculation of consulting program" (Expand search), "dft calculation of computador program" (Expand search), "dft calculation of computer programs" (Expand search), "dft calculations of computing program" (Expand search), "cost calculation of computing program" (Expand search), "_ calculation of computing program" (Expand search), "dft calculation fog computing program" (Expand search), "dft calculation _ computing program" (Expand search), "dft calculation and computing 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: "((\"dft calculation of computing program\") OR (\"advanced computation and computer program\"))~".
• Removing quotes may allow a broader search: (( dft calculation of computing program ) OR ( advanced computation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("dft calculation of computing program") OR ("advanced computation and computer program"))*.
