 | `recovery_alpha_fast` | Exponential decay rate for the fast average weight filter, used in deciding when to recover from a bad approximation by adding random poses. | ✅ | ✅ |
 | `recovery_alpha_slow` | Exponential decay rate for the slow average weight filter, used in deciding when to recover from a bad approximation by adding random poses. | ✅ | ✅ |
 | `resample_interval` | Number of filter updates required before resampling. | ✅ | ✅ |
-| `selective_resampling` | When set to true, it will reduce the resampling rate when not needed and help avoid particle deprivation. The resampling will only happen if the effective number of particles $(N_{eff} = 1/ {\sum w_i^2})$ is lower than half the current number of particles where $w_i$ refers to the normalized weight of particle $i$ [[2]](#2). _This feature is currently supported by Nav AMCL in ROS 1 but it hasn't been ported to ROS 2 at the time of this writing._ | | ✅ |
+| `selective_resampling` | Whether to enable selective resampling [[2]](#2) to help avoid loss of diversity in the particle population. The resampling step will only happen if the effective number of particles $(N_{eff} = 1/ {\sum w_i^2})$ is lower than half the current number of particles, where $w_i$ refers to the normalized weight of each particle. _This feature is currently supported by Nav AMCL in ROS 1 but it hasn't been ported to ROS 2 at the time of this writing._ | | ✅ |
 | `update_min_a` | Rotational movement required from last resample for resampling to happen again. _Nav2 AMCL skips the filter update completely while Beluga AMCL only skips the resampling step. Sensor and motion updates are not skipped._ | ✅ | ✅ |
 | `update_min_d` | Translational movement required from last resample for resampling to happen again. _Nav2 AMCL skips the filter update completely while Beluga AMCL only skips the resampling step. Sensor and motion updates are not skipped._ | ✅ | ✅ |
 | `execution_policy` | Execution policy used to apply the motion update and importance weight steps to each particle [`seq`: sequential, `par`: parallel]. | | ✅ |
