Constraint Programming (CP) is an emergent field in operations research[1]. It is based onfeasibility(i.e. finding a feasible solution) rather than optimization (i.e. finding an optimal solution) and focuses on the constraints and variables’ domain rather than the objective function. Although ...
” Eugene C. Freuder, Constraints, April 1997 “Were you to ask me which programming paradigm is likely to gain most in commercial significance over the next 5 years I’d have to pick Constraint Logic Programming, even though it’s perhaps currently one of the least known and understood.”...
What is a constraint in database? What is database design? What is a flat database? What is dynamic database? What is a RDBMS database? What is a data instance? What is the V-model? What is database programming? What is data granularity?
How do you know if a linear program is unbounded? What is a non linear function? What is the linear relationship between 4x + 6y = 12 and 2x + 3y = 6? What is binding constraint in linear programming? How to write min(a,b,c) as a linear programming problem?
Before C# 13,ref structtypes couldn't be declared as the type argument for a generic type or method. Now, generic type declarations can add an anti-constraint,allows ref struct. This anti-constraint declares that the type argument supplied for that type parameter can be aref structtype. The ...
The Microsoft .NET Framework base class library (BCL) is all about fundamentals. Although some of the basic constructs are stable and don’t change very much (for example, System.Int32 and System.String), Microsoft is still investing a great deal in this space. This article co...

1. "unique" Identity Constraint - A repeating set of attributes or elements are specified as a unique identity. Their values must be unique, if exist. "unique" identity constraint is very similar to the concept of UNIQUE constraint on multiple columns in a database table. ...
REST is one of the most influential ideas in distributed architecture. Here's why it matters and how to understand RESTful services in theory and practice.
