Ensemble Kalman Filter (EnKF) based data assimilation algorithms synthesize predictive numerical forecast models with accumulated data as time evolves and account for model uncertainty and noisy measurements. The computational cost of these algorithms can be expensive, in particular for highly dimensional dynamical systems. Often, EnKF based algorithms have traded accuracy for reduced computational cost. In this paper, we present a novel paralle... Read more ›

In the classic online stochastic matching proposed by Feldman et al. (FOCS 2009), there is a known bipartite type-graph, where one side of the graph is given offline. Upon the arrival of each online vertex, its type is sampled independently and identically from the other side of the type-graph. This model has been extensively studied over the past decade, yielding a rich body of theoretical results. In this paper, we initiate the study of an edg... Read more ›

One of the most common questions developers ask when working with ClickHouse® is: "How should I store JSON data?" The answer isn't as simple as choosing between a String column and the native JSON data type. It depends on how your application ingests, stores, and queries data. JSON has become the standard format for modern applications. Every API request, application log, event stream, telemetry record, and user interaction is typically represented as JSON before it reaches a database. Its sc... Read more ›

Problem Statement leetcode.com Given an array of coin denominations coins[] and an integer amount, return the minimum number of coins required to make up that amount. If it is not possible to form the amount, return -1. You can use a coin unlimited number of times. Brute Force Intuition For every amount, try using each available coin and recursively solve for the remaining amount. At each step, we explore all possible choices and take the minimum coins among all valid combinations. The same s... Read more ›

In this paper we introduce "graph linear notation" -- a complete graph invariant -- which is positioned as an alternative definition for the finite graphs. This invariant is constructed using an algorithm similar to the algorithm of finding canonical forms of graphs. Storing graph linear notation instead of a regular graph allows us to greatly simplify two major problems: the construction of illustrations for graphs with regards to possible gr... Read more ›

We study exact exponential-time algorithms for Edge Deletion to Cactus. Given a connected graph $G$, the task is to delete a minimum number of edges so that the remaining spanning graph is a connected cactus. Akhtar and Philip (IWOCA 2026) gave an $O^*(3^n)$-time algorithm for the unweighted problem, where $n$ is the number of vertices in the input graph and the $O^*(\cdot)$ notation hides polynomial factors. We improve this bound to $O^*(2^n)$ ... Read more ›

We study the problem of $(1+\varepsilon)$-approximating the number of four-cycles in graphs given as arbitrary order edge streams. We propose two new algorithms based on sampling induced subgraphs. Our first contribution is a two-pass algorithm that uses $\widetilde{O}(\kappa m / \sqrt{T})$ space, where $m$ is the number of edges, $T$ is the number of four-cycles, and $\kappa$ is the graph's degeneracy. This algorithm improves upon existing theo... Read more ›
