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)
"advanced circulation time computing program" » "advanced calculation time computing program" (Expand search), "advanced simulation time computing program" (Expand search), "advanced circulatory time computing program" (Expand search), "advanced circulation time consulting program" (Expand search), "advanced circulation time computador program" (Expand search), "advanced circulation time computer programs" (Expand search), "advanced circulation times computing program" (Expand search), "advanced circulation the computing program" (Expand search), "advanced circulation in computing program" (Expand search), "advanced circulation timely computing program" (Expand search), "advanced circulation edge 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: "((\"advanced circulation time computing program\") OR (\"advanced computation and computer program\"))~".
• Removing quotes may allow a broader search: (( advanced circulation time computing program ) OR ( advanced computation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced circulation time computing program") OR ("advanced computation and computer program"))*.
