ShareOI is a repository that collects algorithm competition learning materials.
The project addresses the need for centralized access to educational resources for competitive programming by gathering presentation slides and lecture materials from across the internet. It operates as a community-contributed collection where materials are organized by topic and author name, accepting submissions in PowerPoint and PDF formats. The repository serves as a curated index of existing resources rather than original educational content.
The tool suits students and competitors preparing for algorithm contests who want a single reference point for finding established teaching materials. It works best as a discovery resource for those seeking presentations on specific algorithmic topics. The project acknowledges related educational initiatives in its recommended reading section, including OI-wiki, other slide collections by different authors, and forum-based resources, positioning itself as one option among several approaches to organizing competitive programming knowledge.
The project maintains an open contribution model where community members can submit materials, and it actively manages copyright concerns by requesting issue reports for any infringing content. Development activity shows engagement from multiple contributors who help expand and organize the collection of materials.
