Problem Description

• Each person (nurse or patient) has a time schedule defining when he/she should do what kind of things

        For example, a patient's time schedule is shown below:

                                 Figure 2: Patient's time schedule

       Which means, the patient can (and only) be served by the nurse during 10:10am and 10:40am .

      Likewise, a nurse's time schedule is shown below:

                                 Figure 3: Nurse's time schedule

       which means, the nurse can only work during 8:00am and 12:00pm or 1:00pm and 6:00pm

•     The algorithm must be consists with the time schedule, that is, the algorithm can't assign a nurse to serve patient or travel to patient's home during her rest time and the patient can not be served during his/her rest time.
