ill defined mathematics

If \ref{eq1} has an infinite set of solutions, one introduces the concept of a normal solution. Learn more about Stack Overflow the company, and our products. More rigorously, what happens is that in this case we can ("well") define a new function $f':X/E\to Y$, as $f'([x])=f(x)$. No, leave fsolve () aside. ill-defined adjective : not easy to see or understand The property's borders are ill-defined. $f\left(\dfrac xy \right) = x+y$ is not well-defined Synonyms: unclear, vague, indistinct, blurred More Synonyms of ill-defined Collins COBUILD Advanced Learner's Dictionary. The parameter choice rule discussed in the article given by $\rho_U(Az_\alpha^\delta,u_\delta) = \delta$ is called the discrepancy principle ([Mo]), or often the Morozov discrepancy principle. Share the Definition of ill on Twitter Twitter. To manage your alert preferences, click on the button below. This can be done by using stabilizing functionals $\Omega[z]$. The number of diagonals only depends on the number of edges, and so it is a well-defined function on $X/E$. There are also other methods for finding $\alpha(\delta)$. If we want $w=\omega_0$ then we have to specify that there can only be finitely many $+$ above $0$. Identify the issues. What can a lawyer do if the client wants him to be acquitted of everything despite serious evidence? This holds under the conditions that the solution of \ref{eq1} is unique and that $M$ is compact (see [Ti3]). had been ill for some years. This is a regularizing minimizing sequence for the functional $f_\delta[z]$ (see [TiAr]), consequently, it converges as $n \rightarrow \infty$ to an element $z_0$. ($F_1$ can be the whole of $Z$.) A problem that is well-stated is half-solved. Lets see what this means in terms of machine learning. The main goal of the present study was to explore the role of sleep in the process of ill-defined problem solving. A function is well defined only if we specify the domain and the codomain, and iff to any element in the domain correspons only one element in the codomain. This means that the statement about $f$ can be taken as a definition, what it formally means is that there exists exactly one such function (and of course it's the square root). (2000). Today's crossword puzzle clue is a general knowledge one: Ill-defined. approximating $z_T$. The inversion of a convolution equation, i.e., the solution for f of an equation of the form f*g=h+epsilon, given g and h, where epsilon is the noise and * denotes the convolution. satisfies three properties above. An ill-conditioned problem is indicated by a large condition number. The following are some of the subfields of topology. Select one of the following options. There is an additional, very useful notion of well-definedness, that was not written (so far) in the other answers, and it is the notion of well-definedness in an equivalence class/quotient space. In this definition it is not assumed that the operator $ R(u,\alpha(\delta))$ is globally single-valued. Let $\Omega[z]$ be a continuous non-negative functional defined on a subset $F_1$ of $Z$ that is everywhere-dense in $Z$ and is such that: a) $z_1 \in F_1$; and b) for every $d > 0$ the set of elements $z$ in $F_1$ for which $\Omega[z] \leq d$, is compact in $F_1$. In the study of problem solving, any problem in which either the starting position, the allowable operations, or the goal state is not clearly specified, or a unique solution cannot be shown to exist. ill-defined. There can be multiple ways of approaching the problem or even recognizing it. My main area of study has been the use of . I cannot understand why it is ill-defined before we agree on what "$$" means. And her occasional criticisms of Mr. Trump, after serving in his administration and often heaping praise on him, may leave her, Post the Definition of ill-defined to Facebook, Share the Definition of ill-defined on Twitter. \end{equation} $$(d\omega)(X_0,\dots,X_{k})=\sum_i(-1)^iX_i(\omega(X_0,\dots \hat X_i\dots X_{k}))+\sum_{i
