One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

To avoid a common pitfall, always keep in mind that arrays (and all other LabVIEW structures) are zero indexedthe first element has an index of zero, the second has an index of one, and so on.

Quadratic assignment problem is a NP-hard combinatorial optimization problem and has been applied in various fields. There are always many zero elements in the flow matrix or distance matrix of the quadratic assignment problem instances which are abstracted from the practical problems. Much computation time can be saved if we can first reduce the size of the problem by using its zero elements.
