Perhaps you should try some spelling variations:
"based computational and complexity program" » "and computational and complexity program" (Expand search), "by computational and complexity program" (Expand search), "based computational and complex program" (Expand search), "based computational and complexity from" (Expand search), "based computational and complexity priors" (Expand search), "based computational fluid complexity program" (Expand search)
"using tool python python programming" » "using tool pythons python programming" (Expand search), "using tool piton python programming" (Expand search), "using tool pitons python programming" (Expand search), "using tools python python programming" (Expand search), "using total python python programming" (Expand search), "using tonal python python programming" (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 and complexity program\") OR (\"using tool python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational and complexity program ) OR ( using tool python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational and complexity program") OR ("using tool python python programming"))*.
