Question

Google search did not yield any ideas or solutions neither did SO search.( One post existed with same title but different motive).

Are there well known algorithms, patterns to resolve dependencies and build a hierarchy of objects.

1. It must be able to build a dependency output tree
2. Handle Circular dependencies

note: I can build one referring to exiting products build with to do this but knowing what is going to happen, how it should happen I will finish it sooner than other solutions.

Scope of this algorithm would be java script dependency manager, Family tree builder and many more things that may build tree or hierarchy structure from specification. For example taking javascript dependency manager here is how the algorithm would work.

Script a dependends

 1. script b 
 2. script c.

and

Script b depends

 1. Script x 
 2. Script y

and

Script x depends

1. Script J

so here is the order of loading the scripts

Script j

  Script a

  Script x, Script y

          Script b

You are looking for topological sorting. You will find lots of information about this on the internet.
