Meaning of Robust from wikipedia- Robustness is the property of being strong and healthy in constitution. When it is transposed into a system, it refers to the ability of tolerating perturbations...- encomp****
7. Note that each dataset is an independent subject, so the dotted lines in the graph have no real meaning only the values at the nodes to focus on. However, the datasets are organized by the number of samples from the smallest to the largest, revealing an increasing trend in CPU time ...
To be more precise, we discuss the problem of statistical robustness of the Markowitz optimizer and show that the latter is not robust, meaning that a few extreme assets prices or returns can lead to irrelevant 'optimal' portfolios. We then propose a robust Markowitz optimizer and show that ...
Port 80 is the HTTP protocol’s default port, meaning you can omit it when typing an address into a web browser. Moreover, this port mapping will ensure that there’s no network port collision at http://localhost:5000 in case you haven’t stopped your local instance of Flask. Remember ...

Furthermore, we adopt the parameterization in [30], meaning that cov(Zi)=Σi and the density function is given by (5)f(zi)=Kdi(η)|Σi|−1∕2{1+c(η)δi2}−12η(1+ηdi),where Kdi(η)=c(η)πdi∕2Γ12η(1+ηdi)Γ12η,with Γ denoting the gamma function, c(η)=...
Uncertainty has different meaning and implications in a number of Robustness The concept of robustness has raised a lot of discussion in the literature on decision-making under uncertainty. Roy (2002) suggested that the term robust can have different meanings depending on the decision-making context...
The materialization indicator attains the values of 1 if the corresponding uncertain parameter retains a physical meaning in the problem and 0 otherwise. The DDU-involved RO models in the above works maintain the advantage of computational tractability of conventional RO problems, since a robust ...
The semantics of the array of quantities under focus and the uneven sources of uncertainty at the continental scale are discussed (following the semantic array programming paradigm), with an effort to offer some minimal guidance on terminology, meaning and methodological limitations not only of the ...
(1995), defined two types of robustness, namely solution robustness and model robustness, meaning that the solution of a robust optimization problem is nearly optimal and nearly feasible in all possible realizations of uncertain parameters, respectively. In robust optimization problems, the random ...
