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