Initial setup

New page

The following files are useful for several discretized control problems listed on the [:Category:AMPL|AMPL Category] page. They need to be saved to the same directory.

<source lang="AMPL">
param T > 0; # End time
param nt > 0; # Number of discretization points in time
param nu > 0; # Number of control discretization points

set I:= 0..nt;
set U:= 0..nu-1;
param uidx {I}; param fix_w; param fix_w;

var w {U} >= 0, <= 1 binary; # control function
var dt {U} >= 0, <= T; # stage length vector
