Multi-objective Group Decision Making: Methods, Software and Applications With Fuzzy Set Techniques

This booklet proposes a suite of versions to explain fuzzy multi-objective choice making (MODM), fuzzy multi-criteria determination making (MCDM), fuzzy crew choice making (GDM) and fuzzy multi-objective team decision-making difficulties, respectively. It additionally supplies a suite of comparable equipment (including algorithms) to resolve those difficulties.

Principles and Practice of Constraint Programming - CP 2005: 11th International Conference, CP 2005, Sitges, Spain, October 1-5, 2005. Proceedings

This publication constitutes the refereed complaints of the eleventh foreign convention on rules and perform of Constraint Programming, CP 2005, held in Sitges, Spain, in October 2005. The forty eight revised complete papers and 22 revised brief papers offered including prolonged abstracts of four invited talks and forty abstracts of contributions to the doctoral scholars application in addition to 7 abstracts of contributions to a platforms demonstration consultation have been conscientiously reviewed and chosen from 164 submissions.

Sample text

This expression is made up of three parts: the numeric literal 1 (which is of type int), the + operator (which represents addition) and another numeric literal 1. 0 to tell Go that this is a float- 29 Types ing point number instead of an integer. Running this program will give you the same result as before. 2 Strings As we saw in chapter 2 a string is a sequence of characters with a definite length used to represent text. Go strings are made up of individual bytes, usually one for each character.

1] gives you the 2nd element not the 1st. Also notice that you see 101 instead of e when you run this program. This is because the character is represented by a byte (remember a byte is an integer). 31 Types One way to think about indexing would be to show it like this instead: "Hello World"1. You'd read that as “The string Hello World sub 1,” “The string Hello World at 1” or “The second character of the string Hello World”. 3. Concatenation uses the same symbol as addition. The Go compiler figures out what to do based on the types of the arguments.

Like integers floating point numbers have a certain size (32 bit or 64 bit). Using a larger sized floating point number increases it's precision. (how many digits it can represent) 3. In addition to numbers there are several other values which can be represented: “not a number” (NaN, for things like 0/0) and positive and negative infinity. (+∞ and −∞) Go has two floating point types: float32 and float64 (also often referred to as single precision and double precision respectively) as well as two additional types for representing complex numbers (numbers with imaginary parts): complex64 and complex128.
