I tried solving Leetcode problem #10( Regular Expression Matching) for fun, ended up spending hours on it. problem Link: I took a naive greedy string construction approach to check if the string s matched the pattern p. That worked for simple cases where: p="a*b" s="aaab" output:True But failed in cases where p ="ab*a*c*a" and s ="aaa", output should be True why greedy string construction failed: the flaw was that a* is not a single choice, it can match "", "a", "aa", "aaa" etc. To determine ...

This is the second article in our series on Triton kernel profiling. In our first post, Triton kernel profiling with NVIDIA Nsight tools, we introduced how to profile and optimize custom Triton GPU kernels on NVIDIA hardware. In this post, we focus specifically on optimizing performance for AI and machine learning workloads on AMD GPUs. […] The post appeared first on . Read more ›

The total biharmonic distance, which is the sum of the biharmonic distance between every pair of nodes in a network, is a key metric for evaluating network connectivity and robustness. In this paper, we study the problem of minimizing the total biharmonic distance by adding $k$ nonexistent edges for a given graph $G$ and budget $k$. The problem is computationally challenging. We show that the objective function of the problem is monotone but not... Read more ›

A decades-long search has revealed signs of a subtle outflow from the Milky Way’s central black hole. Something has been missing from the Milky Way’s central black hole. For more than half a century, astronomers searched for a telltale wind that theory said must be blowing from Sagittarius A* (Sgr A*), the supermassive black hole [...] Read more ›
Achieving quantum advantage remains a milestone in the noisy intermediate-scale quantum era. Without complexity proofs, scaling advantage—where quantum resource requirements grow more slowly than their classical counterparts—is the primary indicator. However, direct applications of quantum optimization algorithms to classically intractable problems have yet to demonstrate this advantage. Here we develop enhanced quantum solvers for the NP-complete one-in-three Boolean satisfiability problem. ... Read more ›
There’s a particular kind of pressure that comes with maintaining software at the very bottom of someone else’s stack. ClickHouse lives in exactly that spot: roughly 1.5 million lines of mostly C++ and tens of millions of tests every single day. So what happens when you start introducing Rust into a codebase like that? Not as a rewrite, but linked into a C++ server with a CMake build process that has to be reproducible and FIPS compliant? In today’s episode, we get into the messy, interesting... Read more ›
When someone asks me what originally got me interested in space exploration, my answer is always the same - the Hubble Deep Field. That image, taken in 1995, came out when I was in middle school, and had an everlasting impact on my sense of place in the universe. It’s since been improved upon by various other images, and even last week the Hubble team released yet another jaw-dropping image of the galaxy cluster MACS0329-0211 which recaptures some of the magic of that original image, and stil...

The field of learning-augmented algorithms has demonstrated that machine-learned predictions can bypass worst-case lower bounds across a wide range of problems. So far, however, the focus has been almost exclusively on polynomial-time algorithms, where predictions improve competitive ratios, approximation guarantees, or running times. In this paper, we raise the question of whether predictions can push the frontier of exact exponential-time algo... Read more ›

Time-series data is one of the most common types of data generated by modern applications. Every log entry, API request, metric, transaction, sensor reading, or user interaction is recorded with a timestamp, making time the primary dimension for analysis. As organizations collect billions of these records, efficiently storing and querying them becomes increasingly challenging. This is where ClickHouse® excels. Although ClickHouse is not a dedicated time-series database, its columnar storage a... Read more ›
leetcode.com Problem Statement Given an integer array nums that may contain duplicates, return all possible subsets (the power set). The solution must not contain duplicate subsets. Brute Force Intuition Generate all possible subsets using the classic Pick / Not Pick recursion. After generating every subset, store them in a Set to remove duplicates. While this works, many duplicate subsets are generated unnecessarily and later filtered out. Complexity Time Complexity: O(2ᴺ × N) Space Complexi... Read more ›
