I would like to confirm whether pgRouting still requires the implementation of the following functions from Boost Graph Library (BGL):</p><ol><li><strong>bandwidth</strong> (<a href=\"https://www.boost.org/doc/libs/1_56_0/libs/graph/doc/bandwidth.html#sec:bandwidth\">Boost Doc</a>)</li><li><strong>ith_bandwidth</strong> (<a href=\"https://www.boost.org/doc/libs/1_56_0/libs/graph/doc/bandwidth.html#sec:ith-bandwidth\">Boost Doc</a>)</li></ol><p>If these functions are no longer needed, I am interested in contributing to pgRouting by implementing the following ordering algorithms:</p><ol start=\"3\"><li><strong>King Ordering</strong> (<a href=\"https://www.boost.org/doc/libs/1_87_0/libs/graph/doc/king_ordering.html\">Boost Doc</a>)</li><li><strong>Minimum Degree Ordering</strong> (<a href=\"https://www.boost.org/doc/libs/1_56_0/libs/graph/doc/minimum_degree_ordering.html\">Boost Doc</a>)</li></ol><p>These algorithms are useful for reducing matrix bandwidth and optimizing graph computations, which could enhance certain pgRouting functionalities.</p><p>If <strong>bandwidth</strong> and <strong>ith_bandwidth</strong> are still needed, I would like to prioritize their implementation. 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>",
