bench is a benchmark comparison case, where Test.py is a program for generating boundaries and initial sampling points. This program is modified from https://github.com/farscape-project/PINNs_Benchmark and https://github.com/walkerchi/ETHz-DLSC_PartB. Thanks to the provider.
The corresponding relationship between the case program is shown in the following table:
| Case | Case Generation | Case Test |
|---|---|---|
| 1 | Test_boundary.py | PGO_BOUNDARY.py |
| 2-4 | Test_Forward1-3.py | PGO_FORWARD1-3.py |
| 5-8 | Test_Gen_Floor1-4.py | PGO_SeaFloor1-4.py |
| 9-12 | Test_Gen_Multi1-4.py | PGO_OBS1-4.py |
| 13 | Test_Performance.py | PGO_PERFORMANCE.py |
Any questions about the code can be directed to [email protected].
Due to the size limit of GitHub file transfer, we provide a more complete version on Baidu Netdisk.
