Dear Christopher, Congratulations on the development of a very useful contagion network model. I have been working along the same issues using production networks (in which economic shocks are considered as disease propagation), which are... |
Dear all, I have a directed graph G with 10,000 nodes. I am interested in identifying (l,r)-cores of G where l and r denote the in-degree and the out-degree of G, respectively. Mathematica has already developed separately: ... |
I use Mathematica 10, 64 windows and have no problem with it. |
Does that mean that in a large model with many variables with subscripts we will have to define all the subscripted variables as functions like a[i_,j_]:=... b[i_,j_]:=... and so on I have been having terrible times with subscripts when I use... |
Hi, With help from some of you guys in this forum I have developed the following Code, which works perfectly. My questions are: 1) how to automate the simulations with varying initial conditions. In the following CODE, a given set of initial... |
Yes, it is what I was after; however, the Manipulate code above does not manipulate the parameters. I run the model and change the parameters but the values of the variables concerned do not change at all. I could not see any problem with your Code.... |
Here are some improvement suggestions: 1) you should use Definition if it is really a definition to be evaluated later on. f[Z_] is not proper in your code and you should write it as f[Z] instead because you use simple assignment rule. 2) do not... |
Dear All, Here is a simple Manipulate within which there is a DO loop. I get an error message and I cannot find where I make the mistake. Could you please help me in finding the source of the error in the attached notebook. Thanks, Jones |
Dear Miguel and Bruce, I have solved my problem with your help. The solution is to write the model equations in Standard Input Form and then using "Convert to" command under "Cell" I convert the Standard form to Traditional form. Thereafter, I... |
I have written the attached Mathematica code for a general equilibrium model? However, I am having problems with running it. The subscripts and superscripts create problem and even sometime a simple assignment n=30 does not work and if it works then... |
