Perhaps you should try some spelling variations:
"advanced computation by computer program" » "advanced computations by computer program" (Expand search), "advanced computational by computer program" (Expand search), "advance computational by computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced computation _ computer program" (Expand search), "advanced computation in computer program" (Expand search), "advanced computation and computer program" (Expand search)
"advanced simulation code computing program" » "advanced modulation code computing program" (Expand search), "advanced calculation code computing program" (Expand search), "advanced simulation code consulting program" (Expand search), "advanced simulation code computador program" (Expand search), "advanced simulation code computer programs" (Expand search), "advanced simulation model computing program" (Expand search), "advanced simulation case computing program" (Expand search), "advanced simulation models computing program" (Expand search), "advanced simulation modern 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 computation by computer program\") OR (\"advanced simulation code computing program\"))~".
• Removing quotes may allow a broader search: (( advanced computation by computer program ) OR ( advanced simulation code computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation by computer program") OR ("advanced simulation code computing program"))*.
