Key Features
Simple configs
Describe your formula and parameters in a small YAML file. No code changes needed.
Your data: CSV/XLSX
Read inputs from CSV or Excel (XLSX) by column name or index. Get clear CSV/XLSX reports out.
Fast on your machine
Runs on your GPU when available; can run on CPU when an OpenCL CPU runtime (e.g., POCL) is installed.
Clear results
Top results table, summary stats, and saved kernel/code for traceability (CSV and XLSX outputs).
Flexible sampling
Random, Sobol, LHS, or Halton — choose what works best without complexity.
How it works
Define a config
Write a small YAML: expr, goal (min/max), samples, top_k, and params.
Load your data
Point to CSV/XLSX columns by name or index, or use constants. Per-parameter or global.
Sample variations
Generate candidates using RNG, Sobol, LHS, or Halton to explore the parameter space.
Compute
QVAL builds an OpenCL kernel for your expression and evaluates all variations on the device.
Get results
QVAL ranks all results, saves the best ones, and generates detailed reports with analysis.
Quick Start

Where to look
output/tutorial/00_minimal/report/report.txt
output/tutorial/00_minimal/code/eval.clCPU execution requires an OpenCL CPU runtime (e.g., POCL). Without it, only GPU devices are used.
