A periodic therapist routing and scheduling problem with center-based rehabilitation using a hybrid discrete differential evolution algorithm

This is the experimental data of the manuscript entitled "A multi-period home-based therapist routing and scheduling problem considering center-based rehabilitation using a hybrid discrete differential evolution algorithm". All data are generated based on the benchmark instance from Solomon instances (Solomon, 1987) and Gehring and Homberger instances (Gehring & Homberger, 1999) and saved in the file with pkl format. 8 C-type instances, 8 R-type instances, and 4 RC-type instances from Solomon instances are selected and expanded into 40 small-scale and 40 medium-scale instances, and 5 Gehring and Homberger instances are adapted to generate 10 large-scale instances. These instances are distinguished by the number of patients. For example, instance C102-30 represents instance C102 is a small scale instance containing 30 patients.
