solverthe

Solverthe is a software framework designed to support the construction and execution of solver-based workflows across multiple domains. It provides a modular environment in which users can assemble problem definitions, connect diverse solving engines, and manage the flow of data between stages. The goal of solverthe is to enable experimentation with hybrid solving strategies by allowing pipelines that combine constraint solvers, mathematical optimization tools, and heuristic search algorithms.

Origin and development

The project originated as an open-source initiative by a fictitious research group focused on problem solving. The first public releases emphasized interoperability and a plug-in architecture that would allow new solvers to be added without changing core components. Over time, solverthe expanded to include a domain-specific language for defining problem pipelines and a set of adapters to popular solver technologies.

Architecture

Solverthe comprises three core layers: a problem representation layer that encodes problems in a domain-agnostic format; a solver orchestration layer that schedules and runs solver adapters; and a results layer that collects, stores, and analyzes outcomes. A domain-specific language, sometimes referred to as SolvScript, is used to express problem definitions and the sequence of solver steps. The framework emphasizes reproducibility by logging configurations, inputs, and intermediate results.

Applications

Solverthe has been applied in operations research for scheduling and logistics optimization, workforce planning, and engineering design optimization. It is also used in AI planning experiments and academic research on solver composition and orchestration.

Reception

In academic and developer communities, solverthe is valued for its modularity and emphasis on interoperability, though its complexity and the need to maintain solver adapters can be barriers to adoption. Related tools include OR-Tools, Z3, and PuLP.
