Perhaps you should try some spelling variations:
decrease halting » decrease walking (Expand search), decreases healing (Expand search), decreases handling (Expand search)
halting problem » routing problem (Expand search), packing problem (Expand search), cutting problem (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
in decrease » in decreased (Expand search), and decrease (Expand search), can decrease (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: "(( decrease in decrease halting problem ) OR ( decrease faster decrease OR decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease halting problem ) OR ( decrease faster decrease OR decrease ))*.
