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 [60], the wall-clock time (not CPU time) for obtaining the output through JJJJ = -31946 was 1 second, not including the time for “Creating .EXE file" (8 seconds, total, including the time for “Creating .EXE file"). The (-1 3) shown above is a dominated point. One can compare the computational results above with those in Sharma, Dahiya, and Verma [54, pp. 1926-1927, Example 2].

Solving a Multi-Objective Integer Nonlinear Programming Problem with the Epsilon-Constraint Method
Jsun Yui Wong
The computer program listed below seeks to solve the following 3-objective integer nonlinear programming problem from Sharma [52, p. 149]:
Maximize ((2 * X(1) + X(2)) / (X(2) + 2)) ^ 2
maximize (X(1) / (X(2) + 1)) ^ 2
maximize ((X(1) + 2) / (2 * X(1) + X(2) + 2)) ^ 2

This BASIC computer program was run with QB64v1000-win [59]. The complete output of a single run through JJJJ= -31992 is shown below:

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 [59], the wall-clock time (not CPU time) for obtaining the output through JJJJ = -31992 was 2 seconds, not including the time for “Creating .EXE file" (11 seconds, total, including the time for “Creating .EXE file"). One can compare the computational results above with those in Sharma [52, p. 151].

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 [59], the wall-clock time (not CPU time) for obtaining the output through JJJJ = -31962 was 16 seconds, not including the time for “Creating .EXE file" (23 seconds, total, including the time for “Creating .EXE file"). One can compare the computational results above with those in Das and Roy [15, Table 1, pp. 8-9].

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 [59], the wall-clock time (not CPU time) for obtaining the output through JJJJ = -31962 was 16 seconds, not including the time for “Creating .EXE file" (23 seconds, total, including the time for “Creating .EXE file"). One can compare the computational results above with those in Das and Roy [15, Table 1, pp. 8-9].
