//
//Maxflow analysis in net work.  
//
//This analysis is generaly used to solve by graphical model.
//Show command base example as below.
//

//Syntax
mxmult from_point to_point by amount of span;

//Options
mode:(max min)  //max is max flow mode. min is min flow mode.
start:node no   //start node no at flow in.
end:no          //end node no at flow out

//Net work and flow amount of span are defined as blow figure.




//Hand in data which are linked as upper figure.
hand x y span/
1 2 15
1 4 10
1 3 20
2 5 12
3 4 31
3 6 41
4 2 21
4 5 32
4 6 18
;

//Execute maxflow command by command base.
netflow x y  by span /
mode=max
start=1
end=5
;

//Below is output which show flow out 30+12 from no.5 node.





//Below figure is solving max flow by graphical mode.




//Output show flow amount for each node.
