Adapting to the computer program in Wong [14], the following computer program seeks to solve a k-parallel row ordering problem (k-PROP) of 36 facilities. Each row of the 18 rows has 2 facilities. See Amaral [5]. The data for flows and lengths used here can be found in Yen [15, pages 101-105 for flows and page 106 for lengths]. One notes that these lengths are the lengths of C.4.6 STE36-8 in Yen [15, p. 106].

On a personal computer with a Pentium Dual-Core CPU E5200 @2.50GHz, 2.50 GHz, 960 MB of RAM and qb64v1000-win [13], the wall-clock time for obtaining the output through JJJJ=-31996 was 10 seconds.

Solving a k-Parallel Row Ordering Problem of 5 Rows and 36 Facilities
Jsun Yui Wong
Adapting to the computer program in Wong [14], the following computer program seeks to solve a k-parallel row ordering problem (k-PROP) of 36 facilities with the first four rows each having 7 facilities and the fifth row having 8 facilities. See Amaral [5]. The data for flows and lengths used here can be found in Yen [15, pages 101-105 for flows and page 106 for lengths].

Above there is no rounding by hand; it is just straight copying by hand from the monitor screen.
On a personal computer with a Pentium Dual-Core CPU E5200 @2.50GHz, 2.50 GHz, 960 MB of RAM and qb64v1000-win [13], the wall-clock time for obtaining the output through JJJJ=-31962 was two minutes and a half.

Adapting to the computer program in Wong [14], the following computer program seeks to solve a k-parallel row ordering problem (k-PROP) of 36 facilities with the first four rows each having 7 facilities and the fifth row having 8 facilities. See Amaral [5]. The data for flows and lengths used here can be found in Yen [15, pages 101-105 for flows and page 106 for lengths].

Solving An Instance of a K=4 Parallel Ordering Problem of Layout of 23 Facilities
Jsun Yui Wong
Adapting to the computer program in Wong [12], the following computer program seeks to solve the parallel row ordering problem (PROP) of 23 facilities with the first three rows each with 6 facilities and the fourth row with 5 facilities; see Amaral [5]. The data can be found in Amaral [5] and Anjos [8].

Adapting to the computer program in Wong [12], the following computer program seeks to solve the parallel row ordering problem (PROP) of 23 facilities with the first three rows each with 6 facilities and the fourth row with 5 facilities; see Amaral [5]. The data can be found in Amaral [5] and Anjos [8].

Solving a Single-Row Facility Layout Problem of 30 Facilities of Heragu and Kusiak
Jsun Yui Wong
Adapting to the computer program in Wong [14], the following computer program seeks to solve the single-row facility layout problem of 30 facilities in Heragu and Kusiak [9, Page 9, Problem 8, Table 1]. The lengths are specified below in line 17 through line 30. The 30x30 matrix of line 42 through line 71 below is based on a matrix in Nugent, Vollmann, and Ruml [12].

Solving Another Instance of a Parallel Ordering Problem of 23-Facility Layout
Jsun Yui Wong
Adapting to the computer program in Wong [12], the following computer program seeks to solve the parallel row ordering problem (PROP) of 23 facilities with the first row of 4 facilities and the second row of 19 facilities in Amaral [5, p. 2938, Table A4]. The data can be found in Amaral [5] and Anjos [8]. This is the instance {P23_c, L n/5 ]}, Amaral [5, p. 2938].

Solving a Parallel Ordering Problem of 23-Facility Layout
Jsun Yui Wong
Adapting to the computer program in Wong [12], the following computer program seeks to solve the parallel row ordering problem (PROP) of 23 facilities with the first row of 4 facilities and the second row of 19 facilities from Amaral [5, p. 2938, Table A4]. The data can be found from Amaral [5] and Anjos [8]. This is the instance {P23_a, L n/5 ]}, Amaral [5, p. 2938].

Above there is no rounding by hand; it is just straight copying by hand from the monitor screen.
On a personal computer with a Pentium Dual-Core CPU E5200 @2.50GHz, 2.50 GHz, 960 MB of RAM and qb64v1000-win [10], the wall-clock time for obtaining the output through JJJJ=-31996 was 15 seconds.
