Phenomena modelled
Networks
Connections, spreading processes, and evolving networks.
Who is linked to whom decides what spreads: viruses, rumours, collaborations, and the moment a scattered graph becomes one component.

NetworksClaude Black Hole
When do personal assistants become the center of the social graph?Humans adopt Claudes, delegate their connections, and watch an agent cluster take over the social graph.
NetworksGiant Component
How many random links does it take before most people are in one connected cluster?Random links pile up between people on a ring while a flood spreads from one person along them. Once the mean degree passes 1, a flood can reach most of the graph.
NetworksPreferential Attachment
When newcomers favor the popular, how far ahead can one node get?Nodes join one per tick and link to links-per-node existing nodes, picked with probability proportional to degree. At the defaults (80 nodes, 2 links each) the biggest hub ends with about 20 links.
NetworksVirus on a Network
How dense must the contact network be before an outbreak reaches most of the population?A virus spreads over random contacts. Each tick a susceptible person with an infected contact is infected at virus-spread-chance percent, and infected people recover for good at recovery-chance percent.
NetworksSmall World
How few random shortcuts does it take to halve the time a message needs to reach everyone?A message spreads one hop per tick through a ring of people linked to their nearest neighbors. Rewiring 10% of the links cuts the time to reach everyone from 16 ticks to about 9.
NetworksTeam Assembly
How long until every pair in a rotating cohort has worked together?Each tick one fixed cohort (every team-size-th person) is active, and each member links to someone in it. The network stays split into team-size groups that fill in until nearly every pair is linked.
NetworksDiffusion on a Directed Network
Where does all the value end up when every link is one-way?Node 0 starts with 100 units, and each tick every node passes diffusion-rate percent of its value along its outgoing links. The links form a tree pointing away from node 0, so it all ends in the leaves.
NetworksNetwork Example
How high does link-chance have to climb before nobody is left without a contact?A random contact network for testing links: each of 40 people links to one random other with probability link-chance, force layout arranges the result, and each tick 6% of links flash orange.
