Perhaps you should try some spelling variations:
time complexity » the complexity (Expand search), regime complexity (Expand search), case complexity (Expand search)
testing method » testing methods (Expand search), costing method (Expand search), casting method (Expand search)
using testing » using resting (Expand search), using nesting (Expand search), ring testing (Expand search)
method python » method method (Expand search), python python (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 testing method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder time complexity control program ) OR ( using testing method python programming ))*.
