| KSampler With Restarts (Simple) | | Instead of having a restart segment scheduler, segments will use the same scheduler as the KSampler scheduler. |
| KSampler With Restarts (Advanced) | | Has all the inputs for an Advanced KSampler with all the inputs for restart sampling. It should be noted that there is a possibility for invalid segments when using it to end the denoising process early or starting it late (e.g. 20 steps, start at step 0, end at step 10) and invalid segments will be ignored. An invalid segment means that the closest $t_{\textrm{min}}$ in the noise schedule is higher than the segment's $t_{\textrm{max}}$, so the segment would have restarted the denoising process at $t_{\textrm{max}}$ then try to go to a higher noise level (when it should've gone to a lower noise level near $t_{\textrm{min}}$) which will destroy the sample. |
| KSampler With Restarts (Custom) | | Essentially the same as `KSampler With Restarts (Advanced)` but it takes a `SAMPLER` input like the built in `SamplerCustom` node. Note that it is possible to input samplers that don't work properly or are incompatible with Restart sampling like SDE and UniPC samplers.|
| `RestartScheduler` | | For use with custom sampling: This node will output sigmas like other scheduler nodes with restart segments inserted. Must be used with `RestartSampler`. Like stand alone samplers, the node takes parameters for restart segments and schedules. You may also optionally connect sigmas to it, in which case it will use the supplied sigmas for the main schedule. **Note**: When sigmas are connected, the `steps` and `scheduler` parameters have no effect. |

You may also optionally connect sigmas to it, in which case it will use the supplied sigmas for the main schedule. **Note**: When sigmas are connected, the `steps` and `scheduler` parameters have no effect. Setting `denoise` also can't adjust the steps: it can only shorten the sigmas you pass to the node. |
| `RestartSampler` | | For use with custom sampling: Should be used in conjunction with `RestartScheduler` and takes a `SAMPLER` input. This node arranges for the restart noise to be injected at the appropriate points and delegates to the supplied sampler for actual sampling. |
