Data for "Scheduling coupled tasks with flexible gap for minimization of makespan"

The data contains the original data used in the paper "Scheduling coupled tasks with flexible gap for minimization of makespan". Data sets S1 and S2 contain the extension limit of delay time, which should be used with the Benchmark mentioned in this paper, and the data format is the same as Benchmark. S3 contains all the parameters of the problem. Each case file includes four lines of data, which are the processing time of the first task, the processing time of the second task, the delay time and the extension limit. The parameter settings of the dataset are detailed in the paper.
