For details, please refer to the Eclipse Public License.Īlso, if you are using Ipopt to obtain results for a publication, we politely ask you to point out in your paper that you used Ipopt, and to cite the publication. After all, the goal of open source software is the continuous development and improvement of software. However, if you give away software including Ipopt code (in source code or binary form) and you made changes to the Ipopt source code, you are required to make those changes public and to clearly indicate which modifications you made.

This means, it is available free of charge, also for commercial purposes. The Ipopt package is available from COIN-OR under the EPL (Eclipse Public License) open-source license and includes the source code for Ipopt. The mathematical details of the algorithm can be found in several publications, ,,. Ipopt implements an interior point line search filter method that aims to find a local solution of (NLP). It can be used to solve general nonlinear programming problems of the form Ipopt ( Interior Point Optimizer, pronounced 'Eye-Pea-Opt') is an open source software package for large-scale nonlinear optimization. The documentation consists of the following pages: It includes instructions on how to obtain and compile Ipopt, a description of the interface, user options, etc., as well as a tutorial on how to solve a nonlinear optimization problem with Ipopt. This is a cheap way to Create steel for many IC2 and Gregtech tools and machinary without having an industrial blast furnace.This document is a guide to using Ipopt. Please Note that Traincraft Steel can be converted to IC2/Redpower 2 Steel by making the Traincraft steel in to nuggets, and crafting them back in to ingots. Now you must place the Graphite in the center of the Train Workbench, and place three Iron Ingots across the top to produce Steel Dust! Now simply smelt the Steel Dust in any kind of furnace and you have relatively cheap and easy Steel.Ĭonfirmed to still be working as of with the Mindcrack FTB pack, however there appears to be a minor glitch where the crafting method in the train workbean only be done with singly stacked items that means that only 4 coal can be turned into dust at a time, etc.

Next, take either a clay ball or obsidian block and surround it in 8 of the special coal dust to create Graphite. Place the coal in a two by two square, and it will give you 4 of a special kind of coal dust. You will be using the Train Workbench for the rest of these steps and not the crafting table.

To start off, you will need the Train Workbench and some coal. It is possible to craft steel using Traincraft.
