AI 中文总结
该研究扩展了Baier关于BWT隧道的工作，提出了修补BWT中因存在泄漏而失效的隧道的方法，并对比了普通隧道与修补后隧道的空间开销差异。
AI 中文摘要
我们扩展了Baier关于Burrows-Wheeler变换（BWT）隧道的基础工作，展示了如何修补那些因存在偏离隧道的字符串（即“泄漏”）而无法成为有效隧道的结构，使其转变为有效隧道。将普通隧道添加到BWT中需占用与隧道长度成比例的额外空间，而添加修补后的隧道则需占用该空间再加上与泄漏数量成比例的空间。
英文摘要
We extend Baier's foundationial work on tunnelling Burrows-Wheeler Transforms (BWTs) by showing how something that would be a good tunnel except for a strings that diverge from the tunnel (``leaks'') can be patched and turned into a tunnel. Whereas augmenting a BWT with a normal tunnel takes extra space proportional to the tunnels length, augmenting it with a patched tunnels take that plus space proportional to the number of leaks.
