The recommendation is generated by identifying the user's current position within the prerequisite graph and identifying potential next nodes to which the user could move. Based on the user's past interactions with nodes and/or tasks within the prerequisite graph, the user's likelihood of successfully completing the potential next node is calculated, and a recommendation is made based on this calculated likelihood of the user successfully completing the potential next node.
