  AMPL programming language - CompWisdom   (Site not responding. Last check: 2007-10-28)
In computer science, imperative programming, as opposed to declarative programming, is a programming paradigm that describes computation in terms of a program state and statements that change the program state.
AMPL is both a language and a computing environment for expressing, solving, and analyzing mathematical programming problems (minimizing or maximizing a function of decision variables, subject to constraints on the variables).
AMPL passes problems to solvers by writing files, and it is easy to use the solver interface routines in C or C++ programs that read AMPL expression files and evaluate the expressions and their derivatives for arbitrary purposes.

AMPL is also one of the modeling languages supported by the NEOS Server for Optimization (http://www-neos.mcs.anl.gov/neos/).
Little languages provided an attractive option, since they could be powerful enough to generate complex images in an automated way, but limited enough that users could master the syntax for the language in a reasonable amount of time.
The downside of C/C++ is that programming in the language is difficult and error prone, due to the way low-level memory management and addressing are left in the hands of the programmer.

 Optimization Online - Symbolic-Algebraic Computations in a Modeling Language for Mathematical Programming
Abstract: AMPL is a language and environment for expressing and manipulating mathematical programming problems, i.e., minimizing or maximizing an algebraic objective function subject to algebraic constraints.
AMPL permits separating a model, i.e., a symbolic representation of a class of problems, from the data required to specify a particular problem instance.
The net effect is that hidden symbolic and algebraic manipulations play a significant role in making life easier for AMPL users, who usually want to concentrate on formulating and using their intended mathematical programming problems, rather than worrying about arcane technical details.

Examples include programs for listing LPs, automatic conversion to the LP dual (shell-script as solver), solvers for various nonlinear problems (with first and sometimes second derivatives computed by automatic differentiation), and getting C or Fortran 77 for non-linear constraints, objectives and their first derivatives.
AMPL closely resembles the symbolic algebraic notation that many modelers use to describe mathematical programs, yet it is regular and formal enough to be processed by a computer system; it is particularly notable for the generality of its syntax and for the variety of its indexing operations.
Although algebraic modeling languages are widely used in linear and nonlinear programming applications, their use for combinatorial or discrete optimization has largely been limited to developing integer linear programming models for solution by general-purpose branch-and-bound procedures.

 Principles of Programming Languages: Lecture 1
Over the past four decades, thousands of programming languages have been designed and most have been forgotten, but programming language design is by no means a dead area.
Ultimately, without a semantics, a programming language is just a collection of meaningless phrases; hence, the semantics is the crucial part of a language.
Indeed, a speaker at a conference held in Houston in 1968 declared that the field of programming languages was dead, since we had understood everything about languages; the speaker was (largely) correct in referring to the syntactic problems that we must solve, but was failing entirely to consider the semantic issues involved.

 Interview with Brian Kernighan | Linux Journal
AMPL is a language for specifying optimization problems such as linear programming.
It seems to me that at the time the idea of creating a new language was not to show one's disgust with another language, or to come up with a language consistent or compatible with one's level of discipline or seriousness as a programmer as is the case these days.
The authors use perl as an example language in the Practice of Programming: their comments were that it was good for small programs, but that they would want to use something like Java or C++ for a larger program, in order to take advantage of object-orientation.
