Track conflict Same track can't have talks in different rooms simultaneously
Speaker availability Speaker must be available on scheduled day

Multi-day:

"Day";"Talk ID";"From";"To";"Room";"Title";"Speakers";"Level";"Track"

Markdown Output

Generated alongside CSV with .md extension, includes tables grouped by timeslot (and day for multi-day).

Time Limits

  • Small conferences (< 30 talks): 10-30 seconds
  • Medium conferences (30-100 talks): 30-120 seconds
  • Large conferences (100+ talks): 2-10 minutes

Troubleshooting

Hard score < 0

The schedule has constraint violations. Check for:

  • More talks than available slots
  • Speaker assigned to multiple talks in same slot
  • Speaker not available on scheduled day
  • Too many talks in same track for available parallel slots

Increase time limit or review input data.

Talks not scheduled

Verify CSV parsing - check semicolon separators and quote handling.

Speaker availability not working

Ensure the "Speaker Availability days" column values match the day names in your schedule CSV (e.g., if schedule uses "Wednesday", availability should use "Wednesday" not "Wed").

JVM/Java errors

Ensure JDK 17+ is installed and JAVA_HOME is set correctly.
