Frontier Mechanism

TIG employs a Frontier mechanism that determines which bundles earn rewards. The Frontier evolves so that as more compute enters the TIG network, we target higher quality solutions. This mechanism is employed per block and for each challenge individually.

Determining Qualifiers

In TIG there are two objectives/dimensions attached to bundles that determine the rewards. The first dimension is the Track parameter which is committed to at the start of a benchmark. The second dimension is the average quality of the bundle. Tracks for each challenge can be found in Challenges.

At each block we use these dimensions to determine which bundles qualify for rewards. This is implemented using a Frontier Mechanism. In a given challenge, we do the following: the top $K$ bundles in each track, ranked by quality (with ties decided randomly) are set as the qualifying bundles. If a benchmarker would exceed their cutoff, their remaining bundles are not considered as qualifiers.

This plot shows the reward frontier for the vehicle routing challenge from TIG Challenges. At each track, the distribution of bundle qualities is visualized using both scatter and violin plots. The highlighted points represent the qualifying bundles for this block, while the dashed line indicates the minimum average quality threshold needed to qualify for rewards.
