Reviewing Optimization Results

Learn how to read an optimization's results in Artemis and pick the best-performing combination of your code versions.

Accessing Results

From the Optimisations tab, click a finished optimization to open it. Its detail view has three tabs: Versions, Metrics, and Insights.

Understanding the Results

Performance summary

Each optimization card shows its best solution at a glance — the runtime, CPU, and memory of the strongest combination versus your original code, along with the runner's hardware.

Versions

The Versions tab lists every combination Artemis evaluated.

• Code Version — each row is a version built from a combination of your selected changes (the best and target badges mark the winning and baseline versions).
• Targets Changed — how many targets that version touches.
• Diff — lines added / removed.
• Runtime, CPU Time, Memory Usage — the measured result of each version, each shown with its % change vs. the original (green = better, red = worse).

Metrics

The Metrics tab compares every version across all of your metrics at once — runtime, CPU, memory, and any custom metrics (such as throughput) you extract from logs — each against the baseline.

Switch to Compare to pick any two versions and view them side by side, with mean comparison and run-distribution charts per metric.

Key Insights

The Insights tab breaks the result down per code target.

• Location & Versions — the targets, and the versions chosen for each. Optimization versions are combinations of these.
• Scores — the per-target scores for each version.
• Importance (Runtime / CPU / Memory) — how much each change contributes to each metric, so you can see what's actually driving the improvement.
• Weights & filters — adjust the R / C / M weights, or filter to the most important targets, to reorder by what matters to you.

Selecting the Best Version

• Speed-critical → the version with the best Runtime.
• Memory-limited → the version with the best Memory.
• Balanced → the best combined version (marked in the Versions tab).

Next Steps

After reviewing results you can take further actions on optimized versions.
