Ⅲ java人工蜂群演算法求解TSP問題

一、人工蜂群演算法的介紹

人工蜂群演算法(Artificial Bee Colony, ABC)是由Karaboga於2005年提出的一種新穎的基於群智能的全局優化演算法，其直觀背景來源於蜂群的采蜜行為，蜜蜂根據各自的分工進行不同的活動，並實現蜂群信息的共享和交流，從而找到問題的最優解。人工蜂群演算法屬於群智能演算法的一種。

二、人工蜂群演算法的原理

1、原理

標準的ABC演算法通過模擬實際蜜蜂的采蜜機制將人工蜂群分為3類: 采蜜蜂、觀察蜂和偵察蜂。整個蜂群的目標是尋找花蜜量最大的蜜源。在標準的ABC演算法中，采蜜蜂利用先前的蜜源信息尋找新的蜜源並與觀察蜂分享蜜源信息；觀察蜂在蜂房中等待並依據采蜜蜂分享的信息尋找新的蜜源；偵查蜂的任務是尋找一個新的有價值的蜜源，它們在蜂房附近隨機地尋找蜜源。

假設問題的解空間是。

代碼：

[cpp]view plain

Ⅳ 蜂群演算法屬於初級還是高級

人工蜂群演算法(Artificial Bee Colony, ABC)是由Karaboga於2005年提出的一種新穎的基於群智能的全局優化演算法，版其直觀背景來源於權蜂群的采蜜行為，蜜蜂根據各自的分工進行不同的活動，並實現蜂群信息的共享和交流，從而找到問題的最優解。人工蜂群演算法屬於群智能演算法的一種。

Ⅳ 人工蜂群演算法可以解什麼樣的函數

都是一樣的，為什麼有的會帶上「人工」呢？只是因為這些只能演算法都是「人」仿照動物行為而創造的，所以有時候才會帶上「人工」兩個字。但是指的是一個東西。例如神經網路，也有人喜歡說是人工神經網路

Ⅶ 人工蜂群演算法適合在srm中應用嗎

蜜蜂是一種群居昆蟲，雖然單個昆蟲的行為極其簡單，但是由單個簡單的個體所組成的群體卻表現出極其復雜的行為。真實的蜜蜂種群能夠在任何環境下，以極高的效率從食物源（花朵）中採集花蜜；同時，它們能適應環境的改變。
蜂群產生群體智慧的最小搜索模型包含基本的三個組成要素：食物源、被僱傭的蜜蜂（employed foragers）和未被僱傭的蜜蜂（unemployed foragers）；兩種最為基本的行為模型：為食物源招募（recruit）蜜蜂和放棄（abandon）某個食物源。
(1)食物源：食物源的價值由多方面的因素決定，如：它離蜂巢的遠近，包含花蜜的豐富程度和獲得花蜜的難易程度。使用單一的參數，食物源的「收益率」（profitability），來代表以上各個因素。
(2)被僱用的蜜蜂：也稱引領蜂（Leader），其與所採集的食物源一一對應。引領蜂儲存有某一個食物源的相關信息（相對於蜂巢的距離、方向、食物源的豐富程度等）並且將這些信息以一定的概率與其他蜜蜂分享。
(3)未被僱用的蜜蜂：其主要任務是尋找和開採食物源。有兩種未被僱用的蜜蜂：偵查蜂（Scouter）和跟隨蜂（Follower）。偵察蜂搜索蜂巢附近的新食物源；跟隨蜂等在蜂巢裡面並通過與引領蜂分享相關信息找到食物源。一般情況下，偵察蜂的平均數目是蜂群的5%-20%。

Ⅸ 求 人工蜂群演算法用於無線感測器網路路由協議的模擬代碼

我有個基於tinyos的nesc 語言的代碼模擬，不知道你需要不，另外好像這個蟻群演算法好像沒有太大的研究意義。PS.這個不是我的電話號碼

Ⅹ 求人工蜂群演算法的c程序源代碼``````謝謝各位大神了``````
