Highs optimizer

Webimport JuMP highs = JuMP.optimizer_with_attributes (HiGHS.Optimizer, "time_limit" => 30.0 ) solve_des (data, PWLRDWaterModel, highs) Note that this formulation takes much longer to solve to global optimality due to the use of more binary variables. However, because of the finer discretization, a better approximation of the physics is attained. Webusing JuMP using HiGHS. We will define a binary variable (a variable that is either 0 or 1) for each possible number in each possible cell. The meaning of each variable is as follows: x [i,j,k] = 1 if and only if cell (i,j) has number k, where i is the row and j is the column.
