Error in sweep. - parameters: "matsw.sw1","1" The following feature has encountered a problem: - Feature: Stationary Solver 2 (sol4/s2) Failed to find a solution. Maximum number of Newton Iterations reached. Re
*** Reason: Newton solver did not converge because maximum number of iterations reached. *** Where: This error was encountered inside NewtonSolver.cpp. *** Process: 0 *** *** DOLFIN version: 2017.1.0 *** Git changeset: 3d1f687ec9ee39afc0fe6e01800431995b42ad04 *** --- Activity ...
If the maximum number of iterations has not been reached, the optimizer performs iterations until the acceptable cost function is reached or until the optimizer cannot proceed as a result of other optimization setup constraints, such as when it searches for a variable value with a step size small...
studied. The variants are the number of the fireflies, the randomness, the maximum iterations, and the effect of changing the sampling time. A proposed modified firefly is presented with an MPPT controller in the PV system to ensure operating the PV at the MPP. Additionally, the mathematical e...
aligned. Therefore, a number of alternative, more sophisticated approaches needed to be considered, e.g., based on full finite-element models and an explicit compression simulation [38], random-walk based models of curved fibers [39] or the shaking and breaking approach of Li et al. [40]....
The simulation environment is defined by the topography of stations and rail lines, as well as the properties of these, e.g. number of platforms, directionality, gradients, and the maximum line speed. There are two types of agent; trains and passengers. For brevity, from here on in we ...
Regardless of type of conjugate gradient method used, the search direction of the algorithm is reset periodically to the negative value of the gradient. The standard reset takes place when the number of iterations achieves the number of the parameters in the network. There are other reset methods...
where t is the present iteration, T represents the number of maximum iterations, and Rrand refers to a position taken randomly. The random selection of remora also requires an exploration of the search space. The choice of host by the remora depends on whether the host has eaten the prey ...
While wing sweep will increase freestream critical Mach number (MCR) and delay the onset of shocks, it is the supercritical wing design that will expand the range between the MCR and MDD. In terms of range and economy of flight, it is normally not efficient to fly faster than MDD as ...
where l l is the current iteration and L is the total number of iterations. Random numbers c2 and c3 are generated uniformly within the interval [1, 0]. The direction of the jth dimension’s next position movement to positive or negative infinity and step size are determined by c2 and c...
