How to add order / type constraints? about ax

[dqii]

I found this example which was helpful:
https://ax.dev/tutorials/gpei_hartmann_loop.html

And also this code which defined the parameter constraints:

Hi @dqii,

Take a look at https://ax.dev/api/_modules/ax/service/utils/instantiation.html#constraint_from_str

We can parse order constraints of the form "x1 >= x2" from strings, but for more general constraints we suggest using the classes from your other link.

To constrain a variable to be an int with the Loop API you can define it as follows:

        {
            "name": "x1",
            "type": "range",
            "bounds": [0, 10],
            "value_type": "int",  # Optional, defaults to inference from type of "bounds".
        },
