另外,文章使用的是Crocoddyl的FDDP算法(Feasibility-driven Differential Dynamic Programming),是Multiple-shooting DDP的变种,在backward和forward两个pass中都有点区别(具体我没细看引用的文献,感兴趣的可以去了解下),总体来说能够更容易收敛到全局最优。 全身动力学及接触动力学 全身动力学不必多说,相信搞足式运控...
When solving dynamic problems, the equations are discretized by finite element method (or other methods) in space, and then they are transformed into ordinary differential equations [M]{..U}+[C]{.u}+[K]{u}={f}. The two methods for solving this ...
delay differential equationsdynamic programmingThis paper presents a simple implicit time integration scheme for transient response solution of structures under large deformations and long-time durations. The authors focus on a practical method using implicit time integration scheme applied to structural ...
Differential outcomes in academic achievement are also associated with scoring highly on either the incremental or entity beliefs of intelligence. Specifically, it has been found that students who strongly endorse an incremental belief of intelligence tend to receive higher grades than those who endorse ...

In general, according to computational modelings and formulations, meshfree/particle methods can be categorized into two different classifications as well: the weak form formulations of Partial Differential Equations (PDEs); and the strong form formulations of PDEs. The first class of meshfree/particle...
Hint To derive (5.50), write R0 = ρ[FN] and write dR0 in terms of the right and left eigenvectors of FN and the differential of FN. Then expand d(FN) = (dF)N + Fd(N) and apply the vec operator and the chain rule. The right whale The elasticity of R0 is shown in Fig. ...
This paper presents a generalised perturbation form of the nonhydrostatic partial differential equations (PDEs) that govern dynamics of all-scale global atmospheric flows. There can be many alternative perturbation forms for any given system of the governing PDEs, depending on the assumed ambient state...
modification of the standard central differential scheme. The equilibrium is fulfilled at the time t i whereas t i+1 is the unknown state. According to Newton’s axiom the forces which are not in equilibrium cause accelerations which can be integrated to velocities and displacements. The ...
