The limitation of the Pierre Dellacherie algorithm is that the feature weights require manual tuning, and it assumes that the board becomes stationary immediately after a piece lands.

UnverifiedThe heuristic features used by the Pierre Dellacherie algorithm include landing height, number of lines cleared, number of holes, row transitions, column transitions, well depth, and others.70% similarUnverifiedSince the joint lower bound shows that the dependence on (d, δ, ε) cannot be optimized in a decomposed manner, the trade-offs in algorithm design should be placed on improving constants and practical sample reuse efficiency, rather than attempting to break through the product structure of the three in worst-case guarantees.67% similarUnverifiedAlgorithm selection must match the nature of the problem: gradient descent is suited for smooth, differentiable, continuous optimization, while gradient-free methods are suited for discrete, step-wise, or highly noisy objective functions.66% similarUnverified只要优化目标存在漏洞，数学意义上的最优策略就可能天然包含欺骗性行为，这是梯度下降算法的必然产物66% similarUnverifiedNaively approximating the infinite-dimensional functional gradient causes the algorithm to converge to the wrong location, introducing systematic bias.65% similar
