Is the constraint expressed following right? Uncategorized Jan 9, 2023 N juansun Jan 9, 2023 #1 I want to express the constraint like A*x*log2(1+B/x)>=S, where x is a variable. I express it like this -A*rel_entr(x,x+B)/log(2)>=S. Is it right? Thank you. M Mark L. Stone Jan 9, 2023 #2 Yes, that is correct. N juansun Jan 10, 2023 #3 Thank you very much for your response.
