I want to compare variables with constants, like x>p, z=1. x is continuous variables and p is constant, z is binary variable.

I try to solve it with big-M method in Gurobi, I want to know is there any other methods to solve this problem?

  There is currently no automatic way in Gurobi to write conditional statements of the form you presented. We discuss a possible solution in How do I model conditional statements in Gurobi?

  If you have additional information that "if \(z=1\) then \(x>p\)" then you could use indicator constraints.
