The second is a **generic builder** -that accepts several different types of `init_data`. - -### `initial_guess` keyword API - -```julia -ig = CTSolvers.initial_guess(ocp; state=0.0, control=0.1) -``` - -The keyword arguments may be: - -- constants (scalars or vectors) with dimensions consistent with the problem, -- functions of time `t -> x(t)` or `t -> u(t)`, -- `nothing` (use internal defaults). - -The state and control are interpreted using `initial_state` and -`initial_control` helpers, and `initial_guess` always returns a validated -`OptimalControlInitialGuess`. - -### `build_initial_guess(ocp, init_data)` - -`build_initial_guess` is more general and dispatches on the type of -`init_data`: - -```julia -ig = CTSolvers.build_initial_guess(ocp, init_data) -``` - -Supported forms include: - -- `nothing` or `()` → default initial guess. -- an `OptimalControlInitialGuess` instance → returned as is. -- an `OptimalControlPreInit` (from `pre_initial_guess`) → completed and - validated. -- a `CTModels.AbstractSolution` → warm‑start from an existing solution. -- a `NamedTuple` → flexible block / component specification (see below). - -In all cases, the result is validated against the problem dimensions and time -settings. - ---- - -## Warm‑starting from an existing solution - -If you already have a solution `sol` of a related problem (for example after a -previous solve), you can use it directly as an initial guess: - -```julia -using CTModels - -sol = "some CTModels.AbstractSolution" # for illustration -ig = CTSolvers.build_initial_guess(ocp, sol) -``` - -This extracts `state(sol)`, `control(sol)` and `variable(sol)` and wraps them in -an `OptimalControlInitialGuess`, performing consistency checks on state, -control and variable dimensions. - ---- - -## NamedTuple initial guesses - -The most flexible non‑macro interface is to pass a `NamedTuple` with block and -component entries. The allowed keys are: - -- global blocks: `:state`, `:control`, `:variable`, -- aliases based on the OCP names: `Symbol(state_name(ocp))`, - `Symbol(control_name(ocp))`, `Symbol(variable_name(ocp))`, -- component names of state, control and variable (e.g. `:q`, `:v`, `:u1`, `:tf`). - -Example for the simple fixed‑horizon problem above: - -```julia -init_nt = ( - q = t -> sin(t), - v = t -> 1.0, - u = t -> t, -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``` - -Block‑level initialisation is also supported: - -```julia -init_nt = ( - x = t -> [sin(t), 1.0], # whole state block - u = t -> t, -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``` - -Time‑grid based initial guesses are expressed as `(time, data)` tuples: - -```julia -T = [0.0, 0.5, 1.0] -X = [[-1.0, 0.0], [0.0, 0.5], [0.0, 0.0]] -U = [0.0, 0.0, 1.0] - -init_nt = ( - x = (T, X), - u = (T, U), -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``+ - -Component‑wise time grids are supported in the same way by using component -names (`:q`, `:v`, `:u1`, …) as keys. - -All these forms are exercised and checked in -`test/ctmodels/test_ctmodels_initial_guess.jl`. - ---- - -## The `@init` macro - -Writing large `NamedTuple` literals can be verbose. CTSolvers provides a macro -`@init` that offers a small DSL and compiles directly to a validated -`OptimalControlInitialGuess`. - -### Basic usage - -The general form is: - -```julia -ig = @init ocp begin - # alias statements - a = 1.0 - - # time‑dependent component - q(t) := sin(t) - - # time‑dependent block - x(t) := [sin(t), 1.0] - - # time‑grid based init - x(T) := X - u(T) := U - - # constant / variable init - u := 0.1 -end -``` - -The macro returns an `OptimalControlInitialGuess` and internally performs: - -1. Expansion of the DSL into a `NamedTuple` specification. -2. A call to `build_initial_guess(ocp, namedtuple)`. -3. A call to `validate_initial_guess(ocp, ig)`. - -You can therefore pass the result directly to `CommonSolve.solve` or to any -other code that expects an `AbstractOptimalControlInitialGuess`. - -### Accepted DSL forms - -Inside the `begin … end` block, the macro recognises four kinds of lines: - -1. **Aliases** (ordinary Julia assignments) - - ```julia - a = 1.0 - something = sin - ``` - - These are left untouched and can be used in the right‑hand sides of other - specifications. - -2. **Time‑dependent functions** - - ```julia - q(t) := sin(t) - x(t) := [sin(t), 1.0] - u(t) := t - ``` - - The macro converts `lhs(t) := rhs` into a function `t -> rhs` and associates - it with the key `:lhs` (either a component or a block). - -3. **Time‑grid based initialisation** - - ```julia - x(T) := X - u(T) := U - q(Tq) := Dq - ``` - - The macro converts `lhs(T) := rhs` into `(T, rhs)` and associates it with the - key `:lhs`. This is exactly the same structure as the `(time, data)` tuples - accepted by the `NamedTuple` interface. - -4. **Constant / variable form** - - ```julia - q := -1.0 - v := 0.0 - u := 0.1 - tf := 1.0 - ``` - - These are treated as constant initial values for the corresponding block or - component. - -### Relation to the NamedTuple form - -For a fixed‑horizon problem, the following macro call: - -```julia -ig = @init ocp begin - q(t) := sin(t) - v(t) := 1.0 - u(t) := t -end -``` - -is equivalent (up to validation) to - -```julia -init_nt = ( - q = t -> sin(t), - v = t -> 1.0, - u = t -> t, -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``` - -Similarly, a block‑level specification - -```julia -ig = @init ocp begin - x(t) := [sin(t), 1.0] - u(t) := t -end -``` - -corresponds to - -```julia -init_nt = ( - x = t -> [sin(t), 1.0], - u = t -> t, -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``` - -Time‑grid based specifications follow the same pattern: - -```julia -T = [0.0, 0.5, 1.0] -X = [[-1.0, 0.0], [0.0, 0.5], [0.0, 0.0]] -U = [0.0, 0.0, 1.0] - -ig = @init ocp begin - x(T) := X - u(T) := U -end -``` - -is equivalent to - -```julia -init_nt = ( - x = (T, X), - u = (T, U), -) -ig = CTSolvers.build_initial_guess(ocp, init_nt) -``` - -### Logging the expanded initial guess - -For debugging, `@init` supports an optional keyword‑like argument -`log = true` that prints a compact representation of the underlying -`NamedTuple` specification before building the initial guess: - -```julia -ig = @init ocp begin - q(t) := sin(t) - v(t) := 1.0 - u(t) := t -end log = true - -# prints something like: -# (q = t -> sin(t), v = t -> 1.0, u = t -> t) -``` - -This does **not** change the semantics of the macro and is primarily intended -for interactive experimentation. - ---- - -## Changing the backend prefix (advanced) - -Internally, `@init` uses a configurable prefix to decide which module provides -`build_initial_guess` and `validate_initial_guess`. By default this is the -`CTSolvers` module, but the prefix can be changed for advanced use cases: - -```julia -old_prefix = CTSolvers.init_prefix() -CTSolvers.init_prefix!(:MyCustomBackend) - -@assert CTSolvers.init_prefix() == :MyCustomBackend - -# Restore the default prefix -CTSolvers.init_prefix!(old_prefix) -``` - -This is only needed if you want to route the macro expansion to a different -backend module exposing the same API as CTSolvers. diff --git a/ext/CTSolversIpopt.jl b/ext/CTSolversIpopt.jl index 1d39787..811d9c3 100644 --- a/ext/CTSolversIpopt.jl +++ b/ext/CTSolversIpopt.jl @@ -1,73 +1,517 @@ +""" +CTSolversIpopt Extension + +Extension providing Ipopt solver metadata, constructor, and backend interface. +Implements the complete Solvers.Ipopt functionality with proper option definitions. +""" module CTSolversIpopt -using CTSolvers -using NLPModelsIpopt -using NLPModels -using SolverCore - -# default -__nlp_models_ipopt_max_iter() = 1000 -__nlp_models_ipopt_tol() = 1e-8 -__nlp_models_ipopt_print_level() = 5 -__nlp_models_ipopt_mu_strategy() = "adaptive" -__nlp_models_ipopt_linear_solver() = "Mumps" -__nlp_models_ipopt_sb() = "yes" - -function CTSolvers._option_specs(::Type{<:CTSolvers.IpoptSolver}) - return ( - max_iter=CTSolvers.OptionSpec(; +import DocStringExtensions: TYPEDSIGNATURES +import CTSolvers.Solvers +import CTSolvers.Strategies +import CTSolvers.Options +import CTBase.Exceptions +import NLPModelsIpopt +import NLPModels +import SolverCore + +# ============================================================================ +# Metadata Definition +# ============================================================================ + +""" +$(TYPEDSIGNATURES) + +Return metadata defining Ipopt options and their specifications. +""" +function Strategies.metadata(::Type{<:Solvers.Ipopt}) + return Strategies.StrategyMetadata( + # ==================================================================== + # TERMINATION OPTIONS + # ==================================================================== + + Strategies.OptionDefinition(; + name=:tol, + type=Real, + default=1e-8, + description="Desired convergence tolerance (relative).
