The newly proposed algorithm is named as fixed point iteration (FPI); it only involves simple calculations, such as addition, multiplication, division, and square-root. Unlike state-of-the-art methods, there is no matrix inversion operation and can avoid the unstable performance incurred ...

The algorithm based on fixed-point iteration (Eq. 2.115), a natural approach within the DA framework, can outperform the integrator discussed in the previous section in speed, especially for ODEs for which the right-hand sides consist of a large number of arithmetic operations. Similar to the ...
The exact fixed-point proximity algorithm (3.1)–(3.2) has been introduced in [51] for [Math Processing Error]α∈(0,1). Comments for the case [Math Processing Error]α=1 are in order. In this case, iteration (3.1) reduces to [Math Processing Error]uk+1∈proxγ‖⋅‖0(Dvk). (...

The algorithm is based on a fixed-point iteration scheme that takes advantage of the OCP formulation without terminal constraints. Real-time model predictive control In order to implement the algorithm within a real-time MPC framework, a fixed number of fixed-point iterations is considered in each...
现在我们的unfolding algorithm (a.k.a learning to optimize) 手段越发齐全,作者就考虑针对不同具体问题,训练出有针对性的加速算法。也就是要把加速的那一步推广,参数化,使之可以被学习。 (图片来源于原文) 有了这么一个可学习的函数 gθacc ,理论上我们就可以实现在有限步内实现有效收敛。使用上述算法,迭代 ...
