Perhaps you should try some spelling variations:
rebalancing problem » balancing problem (Expand search), balancing problems (Expand search), reasoning problem (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
in discrete » _ discrete (Expand search), of discrete (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease in discrete rebalancing problem ) OR ( decrease during decrease NOT decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in discrete rebalancing problem ) OR ( decrease during decrease not decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in discrete rebalancing problem ) OR ( decrease during decrease not decrease ))*.
