VarD2Item Property

Returns the variable at the (i,j)-th position. Note that the indices can be any scalar (constant for the mathematical model) expression.

Consider for instance

C#

VarD2 x = Variable("x").Represents("flow on arc (i, j)").HasIndices(i, j).IsContinuous().IsNonnegative();

Then:

x[0, 1] is the x-variable for arc (0, 1),
x[i, j] is the x-variable for arc (i, j),
x[0, j] is the x-variable for arc (0, j),
x[source[c], j] is the x-variable for arc (source[c], j), where source[c] is the source node of commodity c.
