However, if they are no longer required, I am interested in contributing to pgRouting by implementing <strong>King Ordering</strong> and <strong>Minimum Degree Ordering</strong>. Would these functions be relevant to pgRouting’s roadmap? I would appreciate your guidance on whether they could be considered as part of my <strong>Google Summer of Code (GSoC) 2025</strong> project idea.</p><p>Looking forward to your feedback.</p><p>Best regards,</p><p><strong>Fan Wu</strong></p><p>Wuhan University</p><br><br><a href=\"https://discourse.osgeo.org/t/inquiry-about-implementing-graph-ordering-algorithms-in-pgrouting-for-gsoc-proposal/113218/1\">Discuss this on our forum.</a>", "@context": "https://www.w3.org/ns/activitystreams" } }
