Formation of letters
Example of using classical search technique   
This movie shows the plans generated using a classical A* search  algorithm. Each letter was planned individually. The approximate planning time for each letter
was 20 seconds.


Hierarchical Planner, eg 1
Example 35 modules
This movie shows the plan generated using our approach for 35 modules. The planning time was approximately 280 miliseconds


Hierarchical example 2
Example of with 245 modules
This movie shows the plan generated using our approach for 245 modules. The planning time was approximately 400 miliseconds


Hierarchical example 3
Example of hierarchical planner with 1715 modules
This movie shows the plan generated using our approach for 1715 modules. The planning time was approximately 6 seconds

Example 4
Example of hierarchical planner with 12005 modules
This movie shows the plan generated using our approach for 12005 modules. The planning time was approximately 2 minutes.
