Hello, Thank you for your reply. Based on the documentation provided about Netlogo extensions, I am not sure if building a Netlogo extension is actually the solution in my case.
I lean towards using the controlling API. I will do my best to explain the model below: I want a java main class to activate my Netlogo simulation in which the turtles will start moving in random directions. At a defined point in time, I want the positions of the turtles retrieved from Netlogo and reported to java. These positions are to be preprocessed in the java main class. Then, the processed data will be sent to an AMPL model to execute an ILP optimization using CPLEX (AMPL API used). After the ILP optimization is complete, a final position (goal generated by the ILP) is disseminated back to the each turtle in Netlogo (Each turtle will now adjust its movement and go to that specific position). The challenge is that I want the Netlogo simulation to keep running while the ILP optimization is being executed. Also, I want the ILP optimization to be triggered several times during one simulation (each time for a different group of turtle). I hope it is clear. Thank you in advance.
