Our main ... Web0730) on 16 March 2024. As the market opened, the uncrossing algorithm discovered an opening price for 3-month Nickel. Unfortunately due to a systems error, LMEselect then allowed a small number of trades to be executed below this lower daily price limit. 2. The LME immediately decided to suspend Nickel trading on LMEselect while the system ...

Webnoted by [5] (for {0,1}-skew-supermodular cases), the uncrossing game naturally arises from the uncrossing procedure of dual solutions, and a Red-win strategy gives rise to a strongly polynomial time uncrossing algorithm. Our strategy in Theorem 1 is applicable to general skew-supermodular cut-covering linear programs beyond that treated in [5]. find births uk
