A package to optimize linear and quadratic problems in QuadraticModel format

(see https://github.com/JuliaSmoothOptimizers/QuadraticModels.jl).

By default, RipQP iterates in the floating-point type of its input QuadraticModel, but it can also perform operations in several floating-point systems if some parameters are modified (see the [documentation](https://JuliaSmoothOptimizers.github.io/RipQP.jl/stable) for more information).

# Basic usage

In this example, we use QPSReader to read a quadratic problem (QAFIRO) from the

Maros and Meszaros dataset.

```julia

using QPSReader, QuadraticModels

using RipQP

qps = readqps("QAFIRO.SIF")

qm = QuadraticModel(qps)

stats = ripqp(qm)

```

To use the multi precision mode (default to :mono) and change the maximum number of iterations:

```julia

stats = ripqp(qm, mode=:multi, itol = InputTol(max_iter=100))

```
