New Frontiers in Combinatorics & Computer Science (2025)
Invitation Only
Participation is by invitation only. All participants must register.
Organizer:
Raghu Meka, UCLA
Meeting Goals:
Since its founding, Theoretical Computer Science (TCS) has drawn on the technical repertoire of combinatorics. Combinatorial insight was used to design algorithms for discrete optimization, as well as to analyze Boolean circuits to show their limitations. More recently, TCS has moved from being a user of combinatorics to an equal partner, with TCS and combinatorics researchers collaborating to solve or make progress on long-standing open problems in combinatorics. Some recent examples of such collaborations include progress on the sunflower conjecture, density of 3-term arithmetic progressions free sets over integers, Mason’s conjecture for matroids.
The Simons Symposium on New Frontiers in Combinatorics & Computer Science will bring together experts from computer science and combinatorics to present and discuss the latest advancements and amplify the interdisciplinary synergy between these areas.

Funding
All Simons Symposium participants are fully funded by the Simons Foundation. Funding includes roundtrip travel, hotel accommodations and reimbursement of local expenses.
Participation & Guest Policy
By confirming their participation, symposium attendees agree to participate fully in the scientific program, arriving on Sunday, August 17 and departing on Saturday, August 23.
No accommodations will be made for partial or remote attendance.
It is against Simons Foundation policy for guests, including children, to accompany participants during the meeting week. Guests are welcome to join prior to or at the conclusion of the symposium at their own expense.

- Economy Class: For flights that are three hours or less to your destination, the maximum allowable class of service is Economy class.
- Premium Economy Class: For flights where the total air travel time (excluding connection time) is more than three hours and less than seven hours per segment to your destination, the maximum allowable class of service is premium economy.
- Business Class: When traveling internationally (or to Hawaii/Alaska) travelers are permitted to travel in Business Class on those segments that are seven hours or more. If the routing is over budget, a premium economy or mixed-class ticket will be booked.

Round-trip ground transportation between Munich International Airport (MUC) or local train stations and Schloss Elmau will be coordinated by the Simons Foundation. Details in this regard will be communicated approximately two weeks in advance of the meeting.
Attendees who booked their travel themselves should communicate their complete arrival and departure information to the Simons Foundation so that proper arrangements can be made on their behalf.
Travel times between Schloss Elmau and MUC or common train stations are as follows:
Munich International Airport: 1.5-2 hours
Munich Central Station: 1.5-2 hours
Garmisch-Partenkirchen Central Station: 20 minutes
Klais Station: 10 minutes
Travel Deviations & Changes after Ticketing
The following travel specifications are considered deviations and will only be accommodated if the cost is less than or equal to the amount the Simons Foundation would pay for a standard round-trip ticket from your home city to the conference city:
- Preferred airline
- Preferred travel class
- Specific flights/flight times
- Travel dates outside those associated with the conference
- Arriving or departing from an airport other than your home city or conference city airports, i.e. multi-segment or triangle trips.
All deviations must be reviewed and approved by the Simons Foundation and, if the cost is more than what would normally be paid, a reimbursement quote must be obtained through the foundation’s travel agency before proceeding to booking and paying for travel out of pocket. All reimbursements for travel booked directly will be paid after the conclusion of the meeting.
Changes After Ticketing
All costs related to changes made to ticketed travel, including name changes, are to be paid for by the participant and are not reimbursable. Please contact the foundation’s travel agency for further assistance.
Personal & Rental Cars
Personal car and rental trips over 250 miles each way requires prior approval from the Simons Foundation via email.
Rental cars must be pre-approved by the Simons Foundation.

On Wednesday of the symposium week, there will be an optional group hike to Leutascher Geisterklamm. Attendees will confirm their hike participation via registration.
https://www.alpenwelt-karwendel.de/leutascher-geister-klamm-mittenwald
Departing on foot from Schloss Elmau, expert guides will lead participants through well-kept trails lined with lush vegetation to the Leutascher Geisterklamm, a magnificent gorge that features a powerful rushing river, blue pools, towering rock formations and the waterfall Leutaschklamm Wasserfallsteig. Participants will traverse various bridges that line the trail, one of which is 40 meters high and offers spectacular views down into the roaring water.
The path through the Geisterklamm leads towards the center of the town of Mittenwald where a bus will be waiting to take participants back to Schloss Elmau for a late lunch.
