Abstract: Technologies for testing resiliency of a data network with real-world accuracy without affecting the flow of production data through the network. A method according to the technologies may include receiving a production data packet and determining a preferred data route toward a destination node for the production data packet based on a first routing information base, wherein the first routing information base includes a database where routes and route metadata are stored according to a routing protocol. The method may also include, receiving a test data packet, and determining an alternate data route toward the destination node for the test data packet based on a second routing information base, wherein the second routing information base simulates an error in the preferred data route. The method may include sending the production data packet to the preferred data route and sending the test data packet to the alternate data route.

Abstract: An unpriced order auction and related market center and process are disclosed which allow posting market centers (e.g., exchanges) to schedule an auction that includes unpriced (Market) orders only. Such unpriced order auction executes at the midpoint of the NBBO, ensuring that the cross reflects the best prices in the entire marketplace, while discouraging the manipulation of the auction price on the posting market center. The disclosed auction also executes concurrently, but separately from the regular continuous matching process.

Abstract: A tracking liquidity order and related market center and process are disclosed which allow posting market centers (e.g. exchanges) to fill routable, smaller orders that would have otherwise routed off the posting market center. Such tracking liquidity orders increase the liquidity of that posting market center and allow it to execute more orders internally, without having to route them to an away market center.

Abstract: A skateboard deck that is both stiff in one dimension and flexible in another dimension is disclosed. The deck includes an elongated body characterized by a longitudinal axis, a plurality of ribs, and a plurality of apertures. The plurality of ribs are long, narrow beams oriented substantially parallel to the longitudinal axis and integral with the bottom of the elongated body. The plurality of apertures are distributed in a plurality of rows also oriented substantially parallel to the longitudinal axis. The ribs and rows of apertures are interposed in an alternating pattern across the width of the deck. The resulting deck is stiff in the longitudinal direction yet flexible with respect to rotation about the longitudinal axis. The deck is therefore flexible enough to enable the front and rear trucks to rotate with respect to one another while still being rigid enough to withstand the weight of the rider.

Abstract: A system for generating algorithmic models comprising a function module to generate a desirability function, an automated machine learning module, and a UI module. The desirability function defines a single desirability value based on an algorithmic model accuracy criteria, criteria for algorithmic model quality, criteria for model fidelity, and criteria for the benefits and cost of model deployment. Specific hard and soft constraints regarding these and other user-defined criteria can also be specified by the user. The automated machine learning module generates an algorithmic model by training the algorithmic model against a model data set, identifying the model with the greatest desirability with respect to all criteria as combined via the desirability function. The UI module generates a user interface to display the overall desirability as well as all model criteria configured by the user. The displayed criteria and desirability are selectable and definable.
