Perhaps you should try some spelling variations:
"advanced computations _ computing program" » "advanced computational _ computing program" (Expand search), "advance computational _ computing program" (Expand search), "advanced communications _ computing program" (Expand search), "advanced computations _ consulting program" (Expand search), "advanced computations _ computer program" (Expand search), "advanced computations _ computador program" (Expand search)
"advanced simulation from simplex program" » "advanced modulation from simplex program" (Expand search), "advanced calculation from simplex program" (Expand search), "advanced simulation from simples program" (Expand search), "advanced simulation from complex program" (Expand search), "advanced simulation from simple program" (Expand search), "advanced simulation from simpler 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 computations _ computing program\") OR (\"advanced simulation from simplex program\"))~".
• Removing quotes may allow a broader search: (( advanced computations _ computing program ) OR ( advanced simulation from simplex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations _ computing program") OR ("advanced simulation from simplex program"))*.
