...In combinatorial optimization problems, it is necessary to avoid convergence to local optima such as points A and B in Figure 2 and obtain a global optimum like C or a good approximation thereof. For this purpose, methods such as the Boltzmann machine, which introduces stochastic fluctuations into the neuron model and performs simulated annealing by controlling the fluctuations, and the chaos neural network, which dynamically searches for multiple local minima using chaos dynamics, have been proposed. *Some of the terminology that refers to "chaos dynamics" is listed below.

…組合せ最適化問題においては,図2の点A,Bのような局所最適解への収束を避けてCのような大局最適解もしくはそのよい近似解を得ることが求められる。このために,ニューロンモデルに確率的ゆらぎを導入しそのコントロールによって模擬徐冷(シミュレーテッドアニーリング)を行うボルツマンマシンやカオスダイナミクスを用いて多数の極小値を動的にサーチするカオスニューラルネットワークなどが提案されている。 ※「カオスダイナミクス」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
