HLPL / VerTeX Modelling Language Documentation

HLPL / VerTeX modelling language

An open MCP server. No authentication, no API key, no sign-up.

HLPL is the domain-specific language the Elytica platform uses to express Mixed Integer Programming and Linear Programming models — algebraic model declarations combined with Python or Lua for data loading and result processing. This server publishes the complete language reference, eight worked models, a library of verified formulation techniques and a full course: 10 documents · 8 worked models · 70 verified formulations · 48 lessons.

What it serves

• The complete syntax reference — structure, sets, constants, variables, objectives, constraints, Python integration, and the restrictions that silently break models if ignored
• Eight worked models — knapsack, facility location, shortest path, TSP, resource-constrained scheduling, PON network planning, office allocation, skill rotation
• Verified formulation techniques — linearizations, packing and covering, network flow, scheduling, location and the classic named problems, each a complete model whose optimum an independent reference solver confirmed
• A 48-lesson course — from first variable through duality, branch-and-bound, network flow, TSP and graph theory
• Chart generation — emitting ECharts visualizations from results

For language models

/llms.txt indexes everything; /llms-full.txt inlines every document in one fetch.

Running models

This server serves documentation only — it does not execute code. The get_interpreter tool returns the WebAssembly build of the interpreter with integrity hashes and usage snippets so you can run models in your own sandbox, or use the editor to run them in the browser.
