Assume that there exists an alternate world where you only need to specify the problem, the computer will find out an algorithm to find it, even better if could you write it in Python. Stop assuming it hapens every day, and this is the magic of constraint programming. Constraint Logic Programming (CLP) is one of the most successful branches of Logic Programming; it attracts the interest of theoreticians and practitioners, and it is currently used in many commercial applications. Since the original proposal, it has developed enormously: many languages and systems are now available either as open source ...

One idea that has been distilled from this research program is to view a constraint as invoking a procedure. This is the basic idea of constraint programming.

What is constraint programming technology? Constraint programming technology is used to find solutions to scheduling and combinatorial optimization problems. It is based primarily on computer science fundamentals, such as logic programming and graph theory, in contrast to mathematical programming, which is based on numerical linear algebra. Solve Einstein’s Logic Puzzle through Constraint Programming in AIMMS July 8, 2015 August 11, 2015 Lei Feng Constraint Programming , Operations Research Constraint Programming , Logic Puzzle A brain teaser has been posed by Albert Einstein, who claimed that 98% of population in the world could not figure it out . Constraint logic programming makes it possible to solve complex combinatorial problems with a minimum amount of code. Introduction: the dif/2 constraint . Often, Prolog programming revolves around constraints on the values of variables, embodied in the notion of unification.

Introduction. The Python constraint module offers solvers for Constraint Satisfaction Problems (CSPs) over finite domains in simple and pure Python. CSP is class of problems which may be represented in terms of variables (a, b, …), domains (a in [1, 2, 3], …), and constraints (a < b, …). Constraint programming is an embedding of constraints in a host language. The first host languages used were logic programming languages, so the field was initially called constraint logic programming.The two paradigms share many important features, like logical variables and backtracking.Today most Prolog implementations include one or more libraries for constraint logic programming. Sudoku as a Constraint Problem Helmut Simonis IC-Parc Imperial College London [email protected] Abstract. Constraint programming hasﬁnally reached the masses, thou-sands of newspaper readers (especially in the UK) are solving their daily constraint problem. They apply complex propagation schemes with

*Mathematical programming versus constraint programming¶ Mathematical programming and constraint programming are two technologies critical to solving complex planning and scheduling problems. At IBM®, we find that knowing both technologies is important in addressing some of the most difficult optimization problems. This collection presents the best of current work on all aspects of constraint logic programming languages, from theory through language implementation. Constraint logic programming, the notion of computing with partial information, is becoming recognized as a way of dramatically improving on the current generation of programming languages.*

This is often done by embedding constraints into a programming language, which is called the host language.Constraint programming originated from a formalization of equalities of terms in Prolog II, leading to a general framework for embedding constraints into a logic programming language. 8 Constraint Logic Programming This chapter describes the extensions primarily designed to support constraint logic programming (CLP), an important declarative programming paradigm with countless practical applications.

Constraint programming is a programming paradigm where relations between variables can be stated in the form of constraints. Constraints differ from the common primitives of other programming languages in that they do not specify a step or sequence of steps to execute but rather the properties of a solution to be found.*

Schools offering Computer Programming degrees can also be found in these popular choices. There is a lot to learn about the logic branch of mathematics, but we can selectively learn some of it to improve our algorithmic thinking when programming.
