Perhaps you should try some spelling variations:
propagation algorithm » approximation algorithm (Expand search), approximation algorithms (Expand search)
algorithm informatics » algorithms informatics (Expand search), algorithms information (Expand search), algorithmic information (Expand search)
coder propagation » mode propagation (Expand search), model propagation (Expand search), modes propagation (Expand search)
using coating » using coatings (Expand search), using rotating (Expand search), using cutting (Expand search)
coating the » coating to (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 propagation algorithm informatics in ) OR ( using coating the python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder propagation algorithm informatics in ) OR ( using coating the python programming ))*.
