Wow, man, imagine being the kind of person that suspends anyone he sees from Gaza during a genocide.
The inhumanity of some Germans is really quite remarkable. Didn’t you get enough of genocide the first time around?
Add social.tchncs.de to the list of Zionist, pro-genocide Mastodon servers.

End Cover for Initial Value Problem: Complete Validated Algorithms with Complexity Analysis

Abstract: We consider the first-order autonomous ordinary differential equation \[ \mathbf{x}' = \mathbf{f}(\mathbf{x}), \] where $\mathbf{f} : \mathbb{R}^n \to \mathbb{R}^n$ is locally Lipschitz. For a box $B_0 \subseteq \mathbb{R}^n$ and $h > 0$, we denote by $\mathrm{IVP}_{\mathbf{f}}(B_0,h)$ the set of solutions $\mathbf{x} : [0,h] \to \mathbb{R}^n$ satisfying \[ \mathbf{x}'(t) = \mathbf{f}(\mathbf{x}(t)), \qquad \mathbf{x}(0) \in B_0 . \]
We present a complete validated algorithm for the following \emph{End Cover Problem}: given $(\mathbf{f}, B_0, \varepsilon, h)$, compute a finite set $\mathcal{C}$ of boxes such that \[ \mathrm{End}_{\mathbf{f}}(B_0,h) \;\subseteq\; \bigcup_{B \in \mathcal{C}} B \;\subseteq\; \mathrm{End}_{\mathbf{f}}(B_0,h) \oplus [-\varepsilon,\varepsilon]^n , \] where \[ \mathrm{End}_{\mathbf{f}}(B_0,h) = \left\{ \mathbf{x}(h) : \mathbf{x} \in \mathrm{IVP}_{\mathbf{f}}(B_0,h) \right\}. \]
Moreover, we provide a complexity analysis of our algorithm and introduce a novel technique for computing the end cover $\mathcal{C}$ based on covering the boundary of $\mathrm{End}_{\mathbf{f}}(B_0,h)$. Finally, we present experimental results demonstrating the practicality of our approach.

This summer, Mikhail Loshchinin set out for Russia on a motorcycle with German plates, reaching the border in Latvia on July 1.
At the Ubylinka checkpoint on the Russian side, he presented his Russian passport.
According to his mother, Olga, he didn’t use his Belgian passport because of the urgency of the trip and to avoid needing a visa.
Russian border guards examined Loshchinin’s phone and likely discovered his many contacts in Ukraine.
After holding him for several…
