If there is a formula
(m=x1 * log2 (x1) + 1) + x2 * (log2 (x2) + 1) + x3 * (log2 (x3) + 1) + x4 * (log2 (x4) + 1)
S.t x1 + x2, x3 and x4=1 this how to evaluate the smallest m? Is too food, really not using matlab mathematical skills are not enough, please everyone a great god give some ideas?
But x logx both of the zha?
