Preferential Attachment

New links favor already-linked nodes, manufacturing power laws from pure growth.

How it works

  • Each newcomer links to old nodes with odds proportional to degree.
  • Early nodes bank an unbeatable head start.
  • Degree histograms freeze into power laws.
Use → Citations, followers, city pull. Seed early visibility deliberately.
Watch out → Assuming the biggest won on merit — arrival time is a hidden engine.
Try it → Simulate 200 nodes attaching preferentially; plot the degree histogram.
