CRS Optimizer by renz

This extension automatically generates, ranks, and visualizes class schedules for UP Diliman students. While it does not necessarily generate the subjective "perfect" schedule, it tries its best to maximize the probable units to be granted during the batch run.

The extension pulls live catalog data directly from the Computerized Registration System (CRS), allowing for the calculation of the statistical probability of securing each class based on real-time slots and demand.

• Toggle between Maximize Slots to algorithmically prioritize classes that maximize your expected yield, or Feasible mode to generate a strict, non-overlapping schedule without duplicates.
• The extension overlays Rate UP Professors (RUPP) metrics directly onto your schedule table so you never have to switch tabs.
• Manage your weekly schedule with a sleek, drag-and-drop calendar. You can also preview alternative schedules to see how alternative sections fit into your week, and lock in your must-have classes with a single click.
• Define specific active days and set "forbidden" time blocks for lunch breaks, org work, or daily commutes.

All data fetching and schedule optimization are executed locally within your browser. No personal data, telemetry, or enrollment credentials are ever collected, transmitted, or stored externally.
