Abstract: A method for verifying source code for a program includes determining that a new version of the source code is available. One or more verification tools are determined to use for verification of the new version of the source code from a verification specification associated with the source code. A plurality of verification tasks to perform for the verification of the new version of the source code are automatically determined from the verification specification associated with the source code. The plurality of verification tasks for the new version of the source code are automatically performed using the one or more verification tools. A determination is then made as to whether the new version of the source code is verified.

Abstract: A constraint solver service of a computing resource service provider performs evaluations of logic problems provided by the service provider's users and/or services by deploying a plurality of constraint solvers to concurrently evaluate the logic problem. Each deployed solver has, or is configured with, different characteristics and/or capabilities than the other solvers; thus, the solvers can have varying execution times and ways of finding a solution. The service may control execution of the solvers using virtual computing resources, such as by installing and configuring a solver to execute in a software container instance. The service receives solver results and delivers them according to a solution strategy such as “first received” to reduce latency or “check for agreement” to validate the solution. An interface allows the provider of the logic problem to select and configure solvers, issue commands and modifications during solver execution, select the solution strategy, and receive the solution.
