TinyLFU+FIFO is in the simulator (<a href="https:&#x2F;&#x2F;github.com&#x2F;ben-manes&#x2F;caffeine&#x2F;wiki&#x2F;Simulator" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ben-manes&#x2F;caffeine&#x2F;wiki&#x2F;Simulator</a>). However, you&#x27;d probably also want the window cache to correct the deficiency outlined in the updated paper (<a href="http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1512.00727.pdf" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1512.00727.pdf</a>). A FIFO version with that isn&#x27;t in the simulator, but would be easy to add.<p>mutli1 trace
