Extract Variable values during optimization

Hello,

Suppose we have defined a variable say X which and a variable Y which is dependent on X values.

When we assign a lower and upper bound for X it can take any continuous value. In my problem Y is dependent on all the values of X that the solver selected during the model run before giving the final optimal variable values. 

1. How can we extract these values of X that solver selected during the course of execution? 

2. How do we loopback these values and assign them one by one to Y during the course of execution?

Regards,

Vaibhav

  Hi,

  Can you give us some more details on this dependency? For example is \( X \leq Y \) or something similar? You might also find this introduction helpful.

  Best regards,

  It sounds like you need a constraint - perhaps a lazy constraint.
