ProfileSet Builder

Overview

The ProfileSet builder is the most critical transformation in the app. It takes the combination specs, the base character profile, and simulation settings, and produces a single .simc file that SimC processes in one run.

File Structure

The generated .simc file has four sections in order:

[1] Global sim options      ← fight_style, max_time, iterations, threads
[2] Base character profile  ← currently equipped gear, talents, etc.
[3] Enemy definitions       ← enemy=add1, enemy=add2 (if >1 target)
[4] ProfileSet entries      ← one per non-baseline combination

Complete Annotated Example

Scenario: 2 trinket options x 2 ring options x 2 enchants = 8 combos. The base (currently equipped) is not a profileset — the remaining 7 are.

# ── SECTION 1: Global options ──────────────────────────

ProfileSet Syntax Rules

• First line uses = (not +=)
• Subsequent lines for the same combo use +=
• Name must be unique, no dots, enclosed in double quotes
• Only include lines that differ from the base profile

Naming Scheme

Names follow the format combo_NNNN (zero-padded 4-digit index):

• The base profile has no profileset entry — its DPS comes from sim.players[0]
• combo_0001 through combo_9999 for profileset entries
• Indexed names avoid SimC’s internal name buffer truncation issues

A manifest Map<string, CombinationSpec> is built alongside the file for parsing results back.

Parsing json2 Output

// Base DPS (currently equipped):
json.sim.players[0].collected_data.dps.mean

// ProfileSet results:
json.profilesets.results[i].mean    // matched by name
json.profilesets.results[i].stddev
json.profilesets.results[i].mean_stddev

Parallel Mode

Always enabled via profileset_work_threads=2:

threads=T (from user config)
profileset_work_threads=2
→ floor(T/2) parallel workers
→ e.g., threads=8 → 4 workers × 2 threads each

Multi-Enemy Configuration

When numEnemies > 1, add enemy definitions after the base profile and before profilesets:

enemy=add1
enemy=add2
enemy=add3

Statistical Noise Detection

Two results are within statistical noise if their confidence intervals overlap:

function areWithinNoise(a: SimResult, b: SimResult): boolean {
  return Math.abs(a.dps - b.dps) < 2 * Math.max(a.meanStdDev, b.meanStdDev);
}
