Perhaps you should try some spelling variations:
decreasing costs » decreasing cost (Expand search), decreasing rest (Expand search), decrease costs (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
during objects » using objects (Expand search), cutting objects (Expand search), warping objects (Expand search)
of decreasing » of increasing (Expand search), by decreasing (Expand search), in decreasing (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to 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 of decreasing costs decrease ) OR ( decrease of decrease during objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decreasing costs decrease ) OR ( decrease of decrease during objects ))*.
