The Operations Research API is a Google Research service that exposes solvers
for high-level optimization problems. These solvers run on Google's
infrastructure and are consumed as a REST API or
gRPC.
Optimization Solvers
The OR API supports the following solvers:
Limitations on usage
All solvers in the OR API are subject to usage quotas. Solvers in Alpha and Beta
stability levels are free to use, but have quotas that limit calls per
minute, input size (which varies by solver), and maximum runtime. These quotas
are subject to change as solver stability and availability evolve.
