CEC2013LSGO

Problem Difficulty Classification

Difficulty Mode	Training Set	Testing Set
easy	8, 9, 13-20	1-7, 10-12
difficult	1-7, 10-12	8, 9, 13-20

Note: When difficulty is ‘all’, both training and testing sets contain all problems (1-20).

CEC2013LSGO proposes 15 large-scale benchmark problems to represent a wider range of realworld large-scale optimization problems.

• Problem Suite Composition：
  CEC2013LSGO contains four major categories of large-scale problems:

  1. Fully-separable functions (F1-F3)

  2. Two types of partially separable functions:

     1. Partially separable functions with a set of non-separable subcomponents and one fully-separable subcomponents (F4-F7)

     2. Partially separable functions with only a set of non-separable subcomponents and no fullyseparable subcomponent (F8-F11)

  3. Two types of overlapping functions:

     1. Overlapping functions with conforming subcomponents (F12-F13)

     2. Overlapping functions with conflicting subcomponents (F14)

  4. Fully-nonseparable functions (F15)

Except for F13 and F14, which are 905-dimensional, the dimensions of other problems are 1000.
