AlgoHour 4.0

ACPC AlgoHour 4.0 is the fourth edition of our flagship monthly competitive programming contest. This online event offers a time-bound, high-energy coding experience designed to test and enhance participants' problem-solving abilities, algorithmic thinking, and coding skills in a challenging yet enjoyable environment. Participants can join anytime within the 48-hour window and solve the problems for a duration of 1 hour. The contest features a set of carefully crafted problems of varying difficulties, catering to a wide range of skill levels. This edition continues the legacy of AlgoHour, providing a platform for students across institutions to learn, compete, and connect with the competitive programming community. Format Team Size: Solo participation only. Duration: Participants can start the contest anytime within the 48-hour window (26th February 2026, 12:00 AM - 28th February 2026, 12:00 AM). Once started, they have a fixed 1-hour window to complete the problems. Problems: Typically 3-4 problems ranging from Easy to Hard difficulty levels. Languages: Code in any standard programming language supported by the platform (C, C++, Java, Python, etc.). Constraints: Contest is purely online. Participants must adhere to the platform's standard rules and anti-plagiarism policies. Participants have a fixed 1-hour window to solve problems once they start within the 48-hour registration window. Objectives: To provide a challenging and engaging competitive programming experience. To allow students to test and improve their coding, algorithmic, and problem-solving skills under time constraints. To foster a sense of community among competitive programmers from various institutions. To offer a flexible, accessible platform for learning and practice. Evaluation Criteria: Accuracy: Number of problems solved correctly. Time Penalty: Time taken to submit correct solutions (on platforms where applicable). Penalties: Incorrect submissions may incur penalties as per the standard CP platform rules. Rankings determined by the standard leaderboard criteria of the chosen platform (e.g., number of problems solved, time penalties). Rewards: Certificates: Digital participation certificates for all participants. Merit Certificates: Digital merit certificates for top performers based on the final leaderboard.
