This gives deterministic, accurate temp memory numbers directly from XLA's allocation plan — no runtime noise, no nvidia-smi polling, no process isolation needed. The profiler builds the actual quantammsim BFGS computation pipeline (data loading, forward pass, batched objective, vmapped solve), compiles with and without jax.checkpoint, and reports: - temp_size_in_bytes (XLA's planned scratch allocation) - cost_analysis flops (compute cost) - inner value_and_grad stats (the BFGS hot loop) Initial CPU results show checkpoint increases temp memory ~15-23% for the quantammsim forward pass, contrary to expectations.

CMA-ES handles ~10 params comfortably — its sweet spot is +5-50 parameters with expensive evaluations. + +Why CMA-ES? +----------- +CMA-ES (Covariance Matrix Adaptation Evolution Strategy) is a derivative-free +optimizer designed for: +- **Expensive black-box evaluations**: Each forward pass costs ~23ms, and + CMA-ES needs only forward passes (no backward pass), so each evaluation + is ~2x cheaper than BFGS. +- **Non-convex landscapes**: The population naturally explores multiple + basins. The covariance matrix adapts to the local curvature, giving + quasi-Newton-like efficiency without computing gradients. +- **Essentially zero hyperparameters**: Population size and sigma0 have + robust defaults from theory. The algorithm self-tunes learning rates, + step sizes, and covariance adaptation. + +What to tune (outer Optuna search): +------------------------------------ +CMA-ES has fewer knobs than BFGS/SGD, so the search space is smaller: + +CMA-ES-specific (~4D): + - cma_es_n_evaluation_points: Fitness averaging (5-50) + - cma_es_n_generations: Budget per restart (50-500) + - cma_es_sigma0: Initial step size (0.1-2.0) — the ONE CMA-ES hyperparameter + - n_parameter_sets: Number of independent restarts (1-4) + +Training window / constraints (~4D): + - bout_offset_days: Window timing + - val_fraction: Validation holdout + - maximum_change: Weight rate limiter + - minimum_weight: Portfolio weight floor + +Initial param center (~4D): + - initial_k_per_day: Momentum sensitivity + - initial_memory_length: EWMA lookback + - initial_raw_exponents: Power-law shape + - initial_pre_exp_scaling: Gradient normalisation + +Note: noise_scale and parameter_init_method still matter (they control +the diversity of starting points for each restart), but sigma0 partially +subsumes their role — CMA-ES will explore away from the init regardless. + +Usage: +------ +python experiments/tune_training_hyperparams_innercmaes.py +python experiments/tune_training_hyperparams_innercmaes.py --quick +python experiments/tune_training_hyperparams_innercmaes.py -n 100 -c 6 --objective mean_oos_sharpe +""" + +import sys +import os +import json +import argparse +import numpy as np +from datetime import datetime +from pathlib import Path +from typing import Dict, Any +from copy import deepcopy + +sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), ".."))) + +from quantammsim.runners.hyperparam_tuner import ( + HyperparamTuner, + HyperparamSpace, + TuningResult, + OUTER_TO_INNER_METRIC, +) +from quantammsim.runners.default_run_fingerprint import run_fingerprint_defaults + + +# ============================================================================= +# Configuration +# ============================================================================= + +TOKENS = ["ETH", "USDC"] + +START_DATE = "2021-01-01 00:00:00" +WFA_END_DATE = "2025-01-01 00:00:00" +HOLDOUT_END_DATE = "2026-01-01 00:00:00" + +RULE = "power_channel" +INITIAL_POOL_VALUE = 1_000_000.0 +FEES = 0.0 +ARB_FEES = 0.0 + +STUDY_DIR = Path(__file__).parent / "hyperparam_studies" +STUDY_NAME = "eth_usdc_innercmaes_v1" + + +# ============================================================================= +# Search Space +# ============================================================================= + +def create_search_space(cycle_days: int = 180) -> HyperparamSpace: + """ + Create search space for CMA-ES inner optimization of power_channel. + + Three groups of parameters: + 1.

When the market price drifts, the pool becomes decentered — one real +balance grows while the other shrinks. The **thermostat** is the mechanism that +re-centers the pool by decaying virtual balances, which shifts the price range +to track the market. + +Re-centering is necessary (it keeps the pool usable and earns fees), but it +creates **arb loss**: each virtual balance update changes the pool's spot price +relative to the market, and arbitrageurs extract value by trading the pool back +to equilibrium. This arb loss is the dominant cost of operating a reClAMM pool +and is closely related to the LVR (Loss-Versus-Rebalancing) framework. + +The question: **can we reduce total arb loss by being smarter about how fast +the thermostat decays virtual balances?** + +## Method 1: Geometric Decay (Baseline / On-chain) + +The Solidity implementation uses exponential decay: + +``` +V_new = V * base^duration +``` + +where `base ≈ 1 - 1/124000` and `duration` is seconds elapsed. This is +front-loaded: the largest virtual balance changes (and therefore the largest +per-step arb losses) happen immediately after the thermostat fires, then decay +exponentially. Early steps are expensive; late steps are nearly free. + +## Method 2: Constant Arc-Length Speed + +The arb loss per thermostat step is proportional to (ΔZ)²/(4X), where +Z = √P·Va - Vb/√P is a geometry-aware thermostat coordinate and X = Ra+Va. +By Cauchy-Schwarz, for a fixed total displacement, total loss is minimised +when per-step loss is *constant* — i.e., when each step covers equal +arc-length in the (Z, X) metric space. + +This requires stepping by ΔZ = 2·speed·√X·dt at each block, where `speed` +is calibrated to match the geometric decay rate at the onset state (the +moment centeredness first crosses the margin threshold). The implementation +solves a quadratic in VB-space to find the virtual balances that achieve +the target Z. + +**Result**: Modest improvement over geometric. On AAVE/ETH (narrow range, +25bps fees, 1 year), constant arc-length saved ~$6,400 in LVR vs geometric +($372,927 vs $379,310). + +## Method 3: Centeredness-Proportional Speed (the winner) + +The key insight: re-centering urgency depends on *how far off-center the pool +is*. A deeply decentered pool accumulates arb losses faster between blocks +(larger price impact per trade), so it should re-center more aggressively. + +The implementation scales the thermostat speed by `margin / centeredness`: + +``` +effective_speed = base_speed * margin / max(centeredness, 1e-10) +``` + +Properties: +- **At onset** (centeredness = margin): multiplier = 1.0. The calibration + against geometric is preserved — the first step is identical. +- **Deeper off-center** (centeredness < margin): multiplier > 1. The pool + re-centers faster, reducing the time spent in high-loss states. +- **No new state**: centeredness is already computed every block from + (Ra, Rb, Va, Vb).
