rl_sorting

Part of the RL module ecosystem; ships in DXPR CMS.

RL: A/B Test Views Content (rl_sorting) is a Views sort plugin that A/B and multivariate tests the order of any Drupal View using reinforcement learning. Every visitor click is human feedback (RLHF-style); the algorithm continuously shifts traffic to higher-performing items. No fixed test horizons. No manual winner picking. No third-party SaaS.

You need this if

• You want to A/B or multivariate test the order of content in a View (blog posts, products, news items, anything Views can list)
• You want to test dozens or hundreds of items simultaneously, not just A vs B
• You want continuous optimization, not fixed-horizon tests with manual setup
• You want fair exposure for new content without manually rotating it

Features

• Multivariate by default: 2 to thousands of items, no per-test setup
• Universal entity support: nodes, users, taxonomy terms, media, custom entities
• Views integration: a single sort plugin you add to any View display
• Real-time RLHF loop: clicks update the model on every page
• Cold-start handling: new items get exploration scores so they get fair exposure
• Time-based filtering: rolling windows for seasonal or campaign content
• Configurable caching: Views cache lifetime auto-aligned with the RL refresh rate
• Privacy-first tracking: anonymous statistics only, GDPR-compliant

How it works

The sort plugin scores every item in the View using a multi-armed bandit (Thompson Sampling) and routes traffic to higher-performing items. JavaScript on the rendered page records views (turns) and clicks (rewards), feeding the model in real time. The RL core handles the math; this module bridges it to Views.

Post-installation

1. Install and enable the RL (Reinforcement Learning) module
2. Configure permissions at /admin/people/permissions
3. Edit any View display and add "RL: A/B Testing" as the sole sort criterion
4. Configure cache refresh rate and time-window options
5. Save; content optimization begins immediately

Migrating from ai_sorting

This module was renamed from ai_sorting in 2026. Existing installs migrate automatically when you enable rl_sorting; experiment history, Views config, and the legacy module are all handled in hook_install. See the 1.0.0-beta1 release notes for details.

Requires

• RL (Reinforcement Learning) module
