Adding an ACT estimate for the walks
Compare changes
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 22 April 2025 starting at approximately 9am PDT. It is expected to take around 30 minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk. This maintenance will be upgrading the GitLab database in order to be ready for the migration.
Improvements to the bilby implemented rwalk method
rwalk a new implementation which calculates an ACT to better estimate the number of steps neededThe rwalk sample method now defaults to bilby.core.sample.dynesty.sample_rwalk_bilby_with_act which adds the maxmcmc, nact. These control the maximum number of walks, the number of ACT required before accepting a point.
Uses the CPNest method to calculate the ACT
Adds a guide to the documentation on using dynesty
Updates the default vol_dec to 8 and enlarge to 1.5 which was found to improve boundary behaviour Note: during development, I experimented with adding a Jacobian and adaptive walks. I found in practise these didn't help sampling so I've removed them for simplicity.
Updates the walks to default to 100. This is now the minimum number of steps.
