let x = the perimeter of square Area = area of square + area of circle Area = (x/4)^2 + pi*((L-x)/2pi)^2 differentiate Area and do some algebra d(Area) = x/8 - L/2pi + x/2pi then set d(Area) = 0 so x = 4L/(pi+4) this is minimum since u can find second derivative...
T(n)= T(n/2)+T(n/2)+T(n/2)= 3T(n/2) 設P(n)=T(2^n), 則P(n)=3P(n-1) P(n)=k*3^n, TIn)=P(log_2(n))= k*3^r (r= log_2(n) ) 3^r= n^[log_2(3)]= n^(log3/log2) 約 n^1.585 故T(n)=k*n^(log3/log2) = O[n^(log3/log2)] 2011-05-21 13:49:51 補充...
