+# Blocks-World (Hierarchical)
+
+This project contains a version of blocks world that is formulated for
+hierarchical task decomposition. It involves three levels of problem spaces.
+There is sufficient evaluation knowledge so that there is no search/uncertainty
+at every level. The top level has a single operator: move-block, which moves a
+block (moving-block) to a destination. The destination can be the top of another
+block or the table.
+
+The next level consists of two operators: pick-up and put-down and they arise in
+an operator no-change for move-block. The rules for these are found under
+move-block. This level introduces the gripper, which can be holding a block or
+empty and is a structure on the top state.
+
+The bottom level has a variety of operators: open-gripper, close-gripper,
+move-gripper-above, move-gripper-down, and move-gripper-up. The structures
+manipulated by these operators are part of the gripper structure on the top state.
+These operators arise in an operator no-change for both pick-up and put-down and
+the rules for them are under pick-up.
+
+Includes gripper status to state. Execution is done through top-state rules that
+simulate changes to the io-link
+
+Works with chunking, which compiles the actions in the substates into rules that
+apply at the top-state. Use the command "learn -e" to turn on chunking, run the agent
+once, init-soar then run the agent again to see how the learned productions eliminate
+the need to subgoal in the second run.
+
+## Soar Capabilities
+
+*   Hierarchical task composition via subgoaling
+*   Internally simulates external environment including an i/o link
+*   Can learn procedural knowledge (enable with 'learn always')

+# Blocks-World (Hierarchical Look-Ahead)
+
+This project augments the [Blocks-World Hierarchical Agent](./blocks-world_(hierarchical))
+with look-ahead state evaluation. The description of the original agent applies
+to this one. The main difference is that look-ahead is performed in the middle of
+the three problem spaces that it uses.
