kadane-adv 1.1.0

About An advanced Python library implementing Kadane’s Algorithm with support for 1D & 2D arrays, visualization, subarray constraints, and test coverage. Perfect for data analysis, time-series problems, and algorithm enthusiasts.

kadane-adv: Advanced Subarray Optimization Library for Python

kadane-adv is a Python package that extends the classic Kadane’s Algorithm to support advanced use cases in 1D and 2D data analysis. Designed for performance and simplicity, it provides efficient tools to identify optimal subarrays and submatrices across diverse datasets—time series, financial data, sensor logs, or image matrices.

It is an essential utility for data analysts, researchers, and machine learning developers seeking meaningful patterns in structured data.

Background

While classic Kadane’s algorithm finds the maximum sum subarray in 1D, kadane-adv extends this by adding:

• Multi-dimensional support (e.g., 2D submatrices)
• Constraint-based searches (e.g., min length)
• Visual feedback to verify or interpret the result

Typical Use Cases:

• Stock market and financial data analysis
• Time series segmentation
• Signal and anomaly detection
• Image processing and matrix evaluation
• Sensor data analysis for IoT applications
