According to https://docs.gurobi.com/projects/optimizer/en/current/reference/numericcodes/opcodes.html this basic operation can not be represented as part of the non-linear API. I am fully aware they can be represented MILP constraints, not but having to do so would be convenient.

  Hi Johann-Tobias,

  Thank you for the request. We are considering adding the abs operator in a future release, but nothing is finalized yet. If you would share a few details about your intended application, it may help us come to a decision.

  Best,

  Robert
