Below is a list of 40 files that represent the 160 instances used for the computational experiments reported in "Minimizing the Number of Tool Switches on a Flexible Machine", International Journal of Flexible Manufucturing Systems 6 (1994), pages 33-54 (authored by Yves Crama, Antoon W.J. Kolen, Alwin G. Oerlemans and myself).

The data in each file is given in the format:
- number of jobs
- number of tools
- capacity C1 of the tool magazine
- tool-job incidence matrix
- name of the instance .

The parameter C1 is as displayed in the second column of Table 2, in the above-mentioned paper. By varying this parameter as shown in Table 2, 160 instances of the tool switching problem can be created.
