Perhaps you should try some spelling variations:
time complexity » the complexity (Expand search), regime complexity (Expand search), case complexity (Expand search)
costing python » costing method (Expand search), using python (Expand search)
using costing » using coating (Expand search), using boosting (Expand search), using coatings (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons 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 costing python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder time complexity control program ) OR ( using costing python python programming ))*.
