SLSQP：When optimizing, it may exceed the limit

[legendfreedom]

f = (x[0]-1)(x[0]-1) + (x[1]-2)(x[1]-2), when Equality constraint: x[0] + x[1] = 3, and Inequality constraint: x[0] >= 1.2,result is ,X: [1.1999999999999993 1.7999999999999994], exceed the limit

Because of how floating-point numbers work, the optimizer needs to rely on a certain “tolerance” to decide when conditions are met. You might try tweaking the constraint a tiny bit—like 1.2000001—to help nudge the optimizer in a more cautious direction.
