<h1>NetworKit Day 2026</h1>
<p><strong>NetworKit Day 2026</strong> is taking place on <strong>November 10th, 2026</strong> online via Zoom, time slot: 2:30pm to 5:30pm CET. </p>
<button type="button" class="btn btn-info" data-toggle="collapse" data-target="#collapse5">Event Details</button><br><div id="collapse5" class="collapse in">
<p><br>This event is about interacting with the community. We share our latest updates,
give insights for new users and also offer two workshops: one for beginners and one for advanced users.
If you want to attend one or more workshops, better be prepared with a notebook and a modern webbrowser
(although it is only for convenience, not a requirement). We also intend to discuss future development
directions and receive feedback on the current status of NetworKit.</p>
<p>NetworKit Day is our recurring community meeting, previously held in 2017, 2020, 2022 and 2024.
ND26 addresses three groups: people who already use NetworKit and want to see what has changed,
people who consider it for a new project, and people who want to help build it. Prior experience
with the toolkit is not required. The beginner workshop starts from scratch and shows how to run
analyses in Jupyter notebooks.</p>
<p>You can register for the event (free of charge) here: <a href="https://www.eventbrite.com/e/networkit-day-2026-nd26-tickets-1999387749581">https://www.eventbrite.com/e/networkit-day-2026-nd26-tickets-1999387749581</a><br>
The registration deadline is November 8th, 2026 (Anywhere on Earth).</p>

<li>3:10pm - 3:45pm : Invited talk by Lutz Oettershagen (University of Liverpool) about "Beyond Static Graphs: Algorithms for Temporal Network Analysis"</li>
<ul>
<li><u>Abstract:</u> Many real-world networks are inherently temporal: interactions occur at specific times,
connections appear and disappear, and the order of events can fundamentally determine what is reachable,
influential, or structurally important. Such evolving systems can be modeled using temporal networks, where
interactions are associated with times and paths must respect the resulting temporal order. Temporal network
analysis therefore calls for algorithmic approaches that go beyond those developed for static graphs. This talk
explores some of the key ideas and computational challenges that arise when time becomes an integral part of the
network model, and presents algorithmic techniques for extracting and understanding structure in evolving networks.
The focus will be on how temporal information changes the way network problems are formulated and solved, as well
as on the challenges of designing methods that remain efficient and scalable on large data sets.</li>

<li>1:30pm - 2:10pm : Scientific Talk: "Robustness of Complex Networks" (Rob Kooij, Tu Delft)</li>
<ul>
<li><u>Abstract:</u> Network Science aims to understand the graph structure of networks and the dynamic
processes that take place on networks. Examples of processes on networks are transport of items
(IP packets with digitalized information, cars, containers) and diffusion (epidemics, electric current,
water flows, human emotions). The Network Architectures and Services Section at the Delft University of
Technology contributes to the fundaments of Network Science: we investigate amongst others geometric
representations of networks, epidemic spread on networks, spectra of graphs and network algorithms. In addition,
we apply our mathematical knowledge to the design, management and control of critical infrastructures, such
as telecom networks and power grids, in order to make these networks robust, resilient, efficient and reliable.
In this talk we will give two examples of our results in the field of robustness of complex networks, namely
robustness of network controllability and cascading failures in power grids.</li>

<h3>LUNCH BREAK</h3>
<ul>
<li>1:30pm - 2:00pm : Scientific Talk: "On Mining Distances out of Massive Time-Evolving Graphs"
(Mattia D'Emidio, University of L’Aquila, Italy)</li>
<ul>
<li><a href="_static/mdemidio_networkit_day_2020.pdf">Presentation Slides</a></li>
<li><u>Abstract:</u> Computing shortest-path distances is a fundamental primitive in the context of graph mining, since this kind of information is essential to a broad range of prominent application domains, including among others network analysis, data routing, web search optimization, and route planning. <br><button type="button" class="btn-link collapsed"></button><div class="collapse"> Textbook approaches for shortest paths (e.g. executing Dijkstra’s algorithm or precomputing a distance matrix) do not scale well with the graph’ size, as they either take seconds to answer a single query on the distance or have a huge memory footprint, when the graph has millions of vertices/arcs. Therefore, to achieve faster query answering and affordable space requirements, smarter and more scalable methods have been designed, the most practical of them being based on a compact representation of the transitive closure of the input graph, called the 2-hop-cover labeling. This talk surveys the main characteristics of such methods, along with some recent algorithms that have been introduced to allow the usage of the 2-hop-cover technique in time-evolving scenarios, i.e. the realistic case when the managed graph undergoes topological modifications over time. We discuss empirical evidences, obtained by experimental evaluations on both real-world and synthetic inputs, that suggest that 2-hop-cover based algorithmic frameworks represent the most promising step forward towards an effective solution for mining distances in general, massive, time-evolving graphs. Most results presented in this talk, as well as most results concerning shortest-path queries in massive complex networks, are of experimental nature and have been achieved also thanks to the recent development of effective toolkits for large-scale graph processing, such as NetworKit. Only a few works with worst-case guarantees are known, and only for special cases (e.g. restrictions on the input): this represents a major open problem that deserves further investigation.</div></li>
