+ *
+ * For ANY and ALL jobs, phase 1 sets the allocation window of each stage to be
+ * [jobArrival, jobDeadline]. For ORDER and ORDER_NO_GAP jobs, the deadline of
+ * each stage is set as succcessorStartTime - the starting time of its
+ * succeeding stage (or jobDeadline if it is the last stage).
+ *
+ * The phases are set using the two functions: 1. setAlgEarliestStartTime 2.
