#1650: v.net.salesman - add sequence output -------------------------+-------------------------------------------------- Reporter: gfleming | Owner: grass-dev@… Type: enhancement | Status: new Priority: normal | Milestone: 6.4.3 Component: Default | Version: unspecified Keywords: | Platform: Unspecified Cpu: Unspecified | -------------------------+--------------------------------------------------
Comment(by mmetz): There is a new option to v.net.salesman in trunk to specify an output file where the sequence is written in tabular format with two columns, sequence and category number. Adding a new column to the attribute table is difficult because 1) several nodes could have the same category value, 2) a single internal node could be visited twice if it is not a user-selected node. The current output in verbose or debug mode in 6.x is correct only in special cases, for somewhat more complex routes, some nodes will be skipped by that output, or not all nodes will be printed. BTW, v.net.salesman in trunk is magnitudes faster than in 6.x, particularly for many (100+) nodes, and solves symmetric and asymmetric TSPs.
