Compatibility bugs with some TSPLIB instances (soon corrected):
|
|
|
|
==> some instances have a space after a section title, for example "NAME :" instead of "NAME:".
|
|
==> several instances have the "COMMENT:" section before the "TYPE:" section.
|
|
==> several section are not yet implemented ("DISPLAY_DATA_TYPE:", ...).
|
|
|
|
Already corrected bugs:
|
|
|
|
==> some instances have several lines with the keyword "COMMENTS:"
