For a system having multiple inputs x and outputs y, the partial coherence is the coherence computed between any individual input and the output when the effect of all other inputs is removed from the output by a linear least squares prediction. This coherence obeys the usual inequality, and will...

In this game there will be a line of 16 squares, you and your opponent will need to put coins into the squares alternately. First, you roll a die to decide which player moves first. Each time when it is your turn, you need to put a pair of coins into two empty adjacent squares, if you cannot do...
