Perhaps you should try some spelling variations:
"based computational complexity sampling program" » "and computational complexity sampling program" (Expand search), "by computational complexity sampling program" (Expand search), "based computational complex sampling program" (Expand search), "based computational complexity scaling program" (Expand search), "based computational community sampling program" (Expand search), "based computational complexity labeling program" (Expand search), "based computational complexity smoking program" (Expand search), "based computational complexity jumping program" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using 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 complexity sampling program\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational complexity sampling program ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational complexity sampling program") OR ("using using python python programming"))*.
