In this paper, we construct several families of iterative methods with memory from one without memory, that is, we ...

(multi-stage) or infinite horizon, and single- and multi-objective ones. Moreover, the nonlinear dependence can appear not only in the objective functions but also in the constraint sets. In this paper, we will consider static one-objective problems in which the nonlinear dependence appears in...
we introduce the general algorithmic framework. The regional tests are presented in Sect.4. Local search over index-1 areas is discussed in Sect.5. In Sect.6we characterize the tests in terms of their completeness. In Sect.7, we address the algorithmic complexity of the problems that we aim...
In practice, the number of Krylov iterations required is observed not to grow as more and more solutions are deflated. 4. Examples. 4.1. Special functions: Painlevé. A well-studied example of an ordinary differential equation boundary-value problem that permits distinct solutions is based on ...
Wherever possible, upper and lower bounds on x should be used to prevent evaluation of nonlinear functions at meaningless points. The Major step limit provides an additional safeguard. The default value r = 2.0 should not affect progress on well behaved problems, but setting r = 0.1 or 0.01 ...
jax-sysid also supports custom loss functions penalizing the deviations of y ^ from y . For example, to identify a system with a binary output, we can use the (modified) cross-entropy lossL ( Y ^ , Y ) = 1 N ∑ k = 0 N − 1 − y k log ( ϵ + y ^ k ) −...
the solution has already been found. A good programming practice is to input the maximum number of times the problem functions are evaluated, and/or an upper bound on the number of iterations. Such bounds are useful in several situations, and serve as a protection against errors in formulation...
