Perhaps you should try some spelling variations:
algorithm informatics » algorithms informatics (Expand search), algorithms information (Expand search), algorithmic information (Expand search)
navigation algorithm » realization algorithm (Expand search), estimation algorithm (Expand search), maximization algorithm (Expand search)
user navigation » based navigation (Expand search), river navigation (Expand search), the navigation (Expand search)
using coping » using coding (Expand search), using coupling (Expand search), nursing coping (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: "(( user navigation algorithm informatics in ) OR ( using coping the python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( user navigation algorithm informatics in ) OR ( using coping the python programming ))*.
