: solution by linear programming[ edit ] the assignment problem can be solved by presenting it as a linear program . for convenience we will present the maximization problem. each edge (i,j), where i is in a and j is in t, has a weight w i j {\displaystyle w_{ij}} . for each edge (i,j) we have a variable
x i j {\displaystyle x_{ij}} . the variable is if the edge is contained in the matching and otherwise, so we set the domain constraints: ≤ x i j ≤ for i , j ∈ a , t , {\displaystyle \leq x_{ij}\leq { ext{ for }}i,j\in a,t,\,} x i j ∈ z for i , j ∈ a , t ....
