| Abstract: | Considering the situation in which some users are controlled while the others still chase their least cost so that the user equilibrium is formed,the efficiency is 1 if the latency functions are linear;and is 1 if 1≤A≤2;and is(A-1)2 if A>2 when the latency functions are nonnegative,non-decreasing and differentiable,where A≥1 is the comparability coefficient of Jacobian matrix of latency functions. |
