-Sometimes there is not one correct ordering for a problem.  For example if you need to initialize a couple of variables and then use them later, but the order you initialize the variables doesn't matter.  If you can specify the order of the blocks as a Directed Acyclic Graph then you can do create a Parsons problem with dependencies.

 Here is a simple example.  The variables a and b can be initialized in either order as long as they are initialized before they are used in the multiplication.
