Perhaps you should try some spelling variations:
time complexity » the complexity (Expand search), regime complexity (Expand search), case complexity (Expand search)
sampling pitons » sampling positions (Expand search), sampling plans (Expand search), sampling plots (Expand search)
using sampling » using subsampling (Expand search), using saline (Expand search), using samples (Expand search)
coder time » cover time (Expand search), modern time (Expand search), over time (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: "(( coder time complexity control program ) OR ( using sampling pitons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder time complexity control program ) OR ( using sampling pitons python programming ))*.
