WebWe perform a simultaneous bifurcation analysis and homotopic continuation between the two synaptic mechanisms with Eq.(9), using the homotopy parameter, h ℎ h italic_h, as a bifurcation parameter. As one model is continuously deformed into the other, at each value of h ∈ [ 0 , 1 ] ℎ 0 1 h\in[0,1] italic_h ∈ [ 0 , 1 ] , the fixed points and their local stability is … WebContinuation / Homotopy算法 同伦 (Homotopy)是拓扑学概念，定义在两个拓扑空间X和Y间的连续函数 f,g:X\rightarrow Y ，若存在一个连续映射 H:X\times [0,1]\rightarrow Y 使 H (x,0)=f (x),H (x,1)=g (x) ，则称H是f,g之间的同伦。 通俗点说，如果一个函数能“连续地形变”为另一个函数，则这两个函数称为同伦的。 上面的Continuation这个词就是表示“连续 …
WebDiscrete continuation method (DCM) is a widely used homotopy method to solve optimal control problems. Starting from auxiliary problem, DCM monotonously varies homotopy parameter until the objective problem is solved. However, DCM often fails when the initially and manually defined homotopy path exists limit points or goes off to infinity.
