Perhaps you should try some spelling variations:
"advanced computational python computer program" » "and computational python computer program" (Expand search), "based computational python computer program" (Expand search), "advanced computacional python computer program" (Expand search), "advanced computacional vpython computer program" (Expand search), "advanced computacionais python computer program" (Expand search)
"an introduction _ scheduling program" » "an introduction _ scheduling problem" (Expand search), "an introduction _ scheduling problems" (Expand search), "an introduction _ scheduling process" (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: "((\"an introduction _ scheduling program\") OR (\"advanced computational python computer program\"))~".
• Removing quotes may allow a broader search: (( an introduction _ scheduling program ) OR ( advanced computational python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("an introduction _ scheduling program") OR ("advanced computational python computer program"))*.
