Perhaps you should try some spelling variations:
"based computational _ computing program" » "and computational _ computing program" (Expand search), "by computational _ computing program" (Expand search), "based computational _ consulting program" (Expand search), "based computational _ computador program" (Expand search), "based computational _ computer programs" (Expand search)
"advanced modulation python computer program" » "advanced calculation python computer program" (Expand search), "advanced oxidation python computer program" (Expand search), "advanced modulation method computer program" (Expand search), "advanced modulation pathway computer program" (Expand search), "advanced modulation cyclone 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: "((\"based computational _ computing program\") OR (\"advanced modulation python computer program\"))~".
• Removing quotes may allow a broader search: (( based computational _ computing program ) OR ( advanced modulation python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational _ computing program") OR ("advanced modulation python computer program"))*.
