資源簡介

越野小汽車機(jī)器人，使用遺傳算法創(chuàng)造出最佳的汽車機(jī)器人。 每一輛汽車獲得一個代表他們的“染色體”，每次根據(jù)上一代基因生成30個小車，其中越野最遠(yuǎn)的小車為此代最優(yōu)基因，下一代小車使用他的基因隨機(jī)變異生成。 當(dāng)小車不移動時會自動死亡，當(dāng)全部小車死亡時會重新生成下一代小車。 當(dāng)點(diǎn)擊左上方下一代按鈕時，選取當(dāng)前跑得最遠(yuǎn)的小車作為最優(yōu)基因生成下一代小車。 按下 再生世界 按鈕清除當(dāng)前跑道數(shù)據(jù)和小車基因數(shù)據(jù)，生成新的跑道和初代小車。 再生設(shè)置可以設(shè)置跑道的長度，彎曲度，彎曲度為最小時跑道沒有上下坡可以進(jìn)行小車賽跑。 參考網(wǎng)站 http://boxcar2d.com
