LogitNELS - Net Logit Equilibrium (Linear Search)
Compute the logit traffic equilibrium using a logit method among LogitB, LogitD, LogitMB, LogitMD the travel time is taken in %net.links.time and the assigned fow is put in the field %net.links.flow of the variable %net which is a NetList which must be declared global.
The equilibrium is computed using a linear search based on the corresponding deterministic criterium as approximated Lyapounov function. This method is valid at least for large theta.
If %net.gp.verbose=%T convergence informations are displayed. These informations are returned by the function in the variable %net.gp.bench.
// Graph generation (the graph must be stongly connected)
%net=TrafficExample("Steenbrink");
//theta definition (almost deterministic)

// Flow calculation
