Justice Ketanji Brown Jackson criticizes Supreme Court emergency rulings
Liberal Justice Ketanji Brown Jackson sharply criticized the Supreme Court on Monday
for being quick to issue rulings that have temporarily allowed some of Donald Trump’s controversial policies to stand
while legal challenges against them play out in the courts.
The justices have signed off on the administration’s ban on transgender soldiers in the military,
the firing of independent agenc…

Abstract: The Cartesian tree of a sequence captures the relative order of the sequence's elements. In recent years, Cartesian tree matching has attracted considerable attention, particularly due to its applications in time series analysis. Consider a text $T$ of length $n$ and a pattern $P$ of length $m$. In the exact Cartesian tree matching problem, the task is to find all length-$m$ fragments of $T$ whose Cartesian tree coincides with the Cartesian tree $CT(P)$ of the pattern. Although the exact version of the problem can be solved in linear time [Park et al., TCS 2020], it remains rather restrictive; for example, it is not robust to outliers in the pattern.
To overcome this limitation, we consider the approximate setting, where the goal is to identify all fragments of $T$ that are close to some string whose Cartesian tree matches $CT(P)$. In this work, we quantify closeness via the widely used Hamming distance metric. For a given integer parameter $k>0$, we present an algorithm that computes all fragments of $T$ that are at Hamming distance at most $k$ from a string whose Cartesian tree matches $CT(P)$. Our algorithm runs in time $\mathcal O(n \sqrt{m} \cdot k^{2.5})$ for $k \leq m^{1/5}$ and in time $\mathcal O(nk^5)$ for $k \geq m^{1/5}$, thereby improving upon the state-of-the-art $\mathcal O(nmk)$-time algorithm of Kim and Han [TCS 2025] in the regime $k = o(m^{1/4})$.
On the way to our solution, we develop a toolbox of independent interest. First, we introduce a new notion of periodicity in Cartesian trees. Then, we lift multiple well-known combinatorial and algorithmic results for string matching and periodicity in strings to Cartesian tree matching and periodicity in Cartesian trees.

When Trump criticized a ruling from a so-called “Obama judge” in 2018,
Chief Justice John G. Roberts Jr. responded that “we do not have Obama judges or Trump judges, Bush judges or Clinton judges.”
But the data suggests that in the 13 appellate courts, there is increasingly such a thing as a Trump judge.
The president’s appointees voted to allow his policies to take effect 133 times and voted against them only 12 times.
Ninety-two percent of their total votes were i…
