Hi,

Is it possible to use a custom function with CP Optimizer?
For example, suppose I want to use the atan2 function which is not provided in the Concert API.
One possibility is to express it using existing functions, but is there a more straightforward way?

Thanks,
Victor

Hello Victor,

Do you mean that you want to write some custom functions which accept IloNumExprArg arguments?
Thus, express them using existing functions is the right way.

For a more complex case you can have a look at
