Welcome. This editor runs a tiny optimization runtime inside your browser — no server, no network. Before we model anything, let's confirm the loop works: edit, run, see output.

The text on the right is Python. Press Run. You should see "Hello, optimizer" in the output panel.

Starter code

def main():
  print("Hello, optimizer")
  return 0

Hint

Click Run. Then change the greeting and run again.

What counts as correct

• no-error — Program finishes without errors
• stdout-contains — Output contains "Hello, optimizer"
