AMPL

AMPL (A Mathematical Programming Language) is an algebraic modeling language to describe and solve high-complexity problems for large-scale mathematical computing (i.e., large-scale optimization and scheduling-type problems).It was developed by Robert Fourer, David Gay, and Brian Kernighan at Bell Laboratories.AMPL supports dozens of solvers, both open source and commercial software, including CBC, CPLEX, FortMP, MINOS, IPOPT, SNOPT, KNITRO, and LGO. Problems are passed to solvers as nl files.AMPL is used by more than 100 corporate clients, and by government agencies and academic institutions. One advantage of AMPL is the similarity of its syntax to the mathematical notation of optimization problems. This allows for a very concise and readable definition of problems in the domain of optimization. Many modern solvers available on the NEOS Server (formerly hosted at the Argonne National Laboratory, currently hosted at the University of Wisconsin, Madison) accept AMPL input. According to the NEOS statistics AMPL is the most popular format for representing mathematical programming problems. (Wikipedia).

What is an Amp?

This electronics video tutorial provides a basic introduction into the amp which is a unit of electric current. It explains how current describes the rate of charge flow and it relates the amp to the number of electrons flowing in a circuit per second. Subscribe: https://www.youtube.com/

What is an Ampere? An Explanation

This video explains what one ampere of current is. Also includes a worked example. The ampere is the derived unit for current in the metric system. When the current in a circuit is one ampere then one coulomb of charge flows past a point in the circuit in one second. One ampere is one

Definition of an Injective Function and Sample Proof

We define what it means for a function to be injective and do a simple proof where we show a specific function is injective. Injective functions are also called one-to-one functions. Useful Math Supplies https://amzn.to/3Y5TGcv My Recording Gear https://amzn.to/3BFvcxp (these are my affil

Schemes 42: Very ample sheaves

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne. We define ample and very ample invertible sheaves for projective varieties, and gives some examples for complex elliptic curves. We also show that some sect
