# ODE-Specialized Physics-Informed Neural Solver

The ODE-specialized physics-informed neural network (PINN) solver is a method for the DifferentialEquations.jl common interface of ODEProblem, which generates the solution via a neural network. Thus the standard ODEProblem is used, but a new algorithm, NNODE, is used to solve the problem.

The algorithm type is:

nnode(chain,opt)

where chain is a DiffEqFlux sciml_train-compatible Chain or FastChain representing a neural network, and opt is an optimization method for sciml_train. For more details, see the DiffEqFlux documentation on sciml_train.
