Jari Saramäki @jsaramak.bsky.social · 06/06/2025It did, but the shortest path required 4 trains instead of 2: trains just dropped passengers at random Dutch stations on the way and told us to wait for the next one 100
Jari Saramäki @jsaramak.bsky.social · 06/06/2025Solution: my cognitive limits prevent me from taking a route involving 4 German regional trains and computing alternatives should any or those connections fail -> waiting for the shortest path to materialize. 100
Jari Saramäki @jsaramak.bsky.social · 06/06/2025Time-respecting path problem: getting by train to Düsseldorf. Your first train is cancelled. Should you wait for a direct connection (to be cancelled with probability p) or pick a route with many hops (p again per hop, but increasing number of alternatives). There must be a DAG for this #NetSci2025 3161
