Results Maritime Transportation - Deep-Sea and Short-Sea Shipping Instances

Each instance has a filename "scip_details_deep_n_i.txt"/"scip_details_short_n_i.txt", in which deep/short indicates that the trips are international/regional (deep sea shipping/short sea shipping), n is the number of ports (including the depot), and i is the index of the instance in the same group.

The data in the file represent the console output of scip. It contains information on:

computation time

gap

primal- and dualbound

best found integer solution

每一实例的文件名格式为"scip_details_deep_n_i.txt"或"scip_details_short_n_i.txt"，其中文件名中的deep与short分别代表该航次对应远洋航线（deep sea shipping）与近洋航线（short sea shipping）；n为港口总数（含基地港（depot）），i为同一分组内该实例的索引。

文件内的数据为SCIP（Solver for Constraint Integer Programs）的控制台输出内容，包含以下信息：
计算时间（computation time）
对偶间隙（gap）
原问题界与对偶问题界（primal- and dualbound）
已找到的最优整数解（best found integer solution）
