Perhaps you should try some spelling variations:
"and computational python computer program" » "and computacional python computer program" (Expand search), "and computacional vpython computer program" (Expand search), "and computacionais python computer program" (Expand search), "_ computational python computer program" (Expand search)
"based compositional data coding program" » "base compositional data coding program" (Expand search), "based compositions data coding program" (Expand search), "varied compositional data coding program" (Expand search), "based compositional data cloning program" (Expand search), "based compositional data loading program" (Expand search), "based compositional data cooling programs" (Expand search), "based compositional data recording program" (Expand search), "based compositional data crossing program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based compositional data coding program") OR ("and computational python computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based compositional data coding program\") OR (\"and computational python computer program\"))*".
• Removing quotes may allow a broader search: (( based compositional data coding program ) OR ( and computational python computer program ))*.
