We can handle the disjunction x 1 ≤ 0 ∨ x 1 ≥ 10 using the Big M method. We introduce binary variables z 1, z 2 ∈ { 0, 1 } such that z 1 + z 2 = 1, i.e., either ( z 1, z 2) = ( 1, 0) or ( z 1, z 2) = ( 0, 1). We introduce also a large constant M ≫ 10 so that we can write the disjunction in the form.
