Summary

  • Computer scientists have long suspected that it’s impossible to solve certain problems using minimal computer memory.
  • However, a theoretical framework called catalytic computing could prove them wrong.
  • The approach was developed by a team of researchers who showed that a full memory can theoretically aid computation.
  • Although the team initially only considered the use of extremely large full memories, other researchers later applied catalytic computing to a standard approach to solving a major open question in computer science, with mixed results.
  • In 2023, two researchers showed that an improved version of the method could solve a specific problem, the tree evaluation problem, using barely more memory than allowed for problems in L.
  • Cook and Mertz’s results have galvanized interest in catalytic computing, with new research exploring its potential.
