Abstract: A computing system generates recommendations for users within the context of a network service. To account for objectives of various users associated with the network service, some of which may not reach optimality at the same time, the computing system generates values associated with each of the objectives separately. For example, for each objective, the system may train a computer model to produce a representative value. To generate a recommendation of an entity for a user, the system uses the generated objective values as inputs to an optimization algorithm. The optimization step may use linear programming or quadratic programming to generate a recommendation score, for example. This two-step process allows the system to account for multiple objectives and makes the system easily adaptable to change when the set of objectives is updated.

Abstract: A delivery coordination system selects restaurant listings for presentation to a user by filtering out restaurants that are unlikely to be of interest to the user, while ensuring that restaurant listings are selected to encourage the success of all restaurants using the delivery coordination system. In response to receiving the listings request from a client device, the delivery coordination system selects a filtered set of restaurant listings from the plurality of restaurant listings stored by the delivery coordination system by applying filtering criteria to the plurality of stored restaurant listings. The delivery coordination system generates conversion scores for the restaurant in the filtered set of restaurant listings and selects restaurant listings to present to the user from the filtered set of restaurant listings based on selection factors, which can include the generated conversion scores. The delivery coordination system transmits the selected restaurant listings to the client device.

Abstract: A test script is divided into tests having a sequential order within the test script. An analysis tree of the tests can be generated. Each unique path through the analysis tree includes a subset of the tests as sequentially ordered within the test script. A maximally parallel subset of the unique paths that covers all the tests and according to which the tests are successfully executable is identified. Each test appears in only one unique path of the maximally parallel subset.

Abstract: A network computing system estimates a provisioning level for a given time interval for one or more regions. The provisioning level determination may be based on an estimated number of order requests, and a number of available service providers in the given region that are available to provide transport in fulfilling the order requests. For individual requesters within the given region, the computer system selects a set of multiple suppliers for a respective supplier menu that is displayed on a mobile device of the requester. The selection of suppliers for individual requesters may be based at least in part on a current location of the requesters, and at least one of the estimated number of order requests or the estimated number of available service providers.

Abstract: A network computer system is provided to fulfill order requests. For each order request, the computer system selects a service provider from a pool of available service providers, to transport a corresponding delivery order from a corresponding supplier to a location of the requester. A provisioning level indicator is determined for a given region and time interval. Based on the provisioning level indicator, the network computer system selectively batches order deliveries.

Abstract: A network computer system operates to arrange transport for delivery orders in a given region, in accordance with a set of provisioning parameters, including a service value parameter, and at least one of a service batching parameter or a service range parameter. For an upcoming time interval, the network computer system determines a forecast for at least one of a number of service requests or a number of available service providers. A provisioning level determination may be made for the given region during the upcoming time interval, based at least in part on the forecast. The set of provisioning parameters may be adjusted to adjust the provisioning level to a desired target.
