In ecology, an ideal free distribution (IFD) is a theoretical way in which a population's individuals distribute themselves among several patches of resources within their environment, in order to minimize resource competition and maximize fitness. The theory states that the number of individual animals that will aggregate in various patches is proportional to the amount of resources available in each. For example, if patch A contains twice as many resources as patch B, there will be twice as many individuals foraging in patch A as in patch B.

| - في علم البيئة، التوزيع الحر المثالي (بالإنجليزية: Ideal free distribution)، هي نظرية بيئية تفيد بأن أفراد الحيوانات تتجمع في بقع مختلفة من الموائل بما يتناسب مع حجم الموارد المتاحة في كلٍ منها. نظرية تفترض أن الحيوانات يمكن أن تتحرك بحرية بين المواقع وأن الأفراد يعرفون مدى عطاء كل رقعة من الموائل. مصطلح «المثالي» يُشير إلى أن الحيوانات تختار العلف مع أعلى مستويات الجودة. مصطلح «الحر» يعني أن الحيوانات قادرة على التحرك دون عوائق من رقعة واحدة إلى أخرى. على الرغم من أن هذه الافتراضات لا يتم دعمها دائما في الطبيعة، لكن لا تزال هناك العديد من التجارب التي أجريت لدعمها.

- 생태학에서 이상적인 자유 분포, 즉 이상자유분포(IFD,Ideal free distribution) 이론은 동물들이 여러 가지 자원으로 분포하는 방식을 설명한다. 이 이론은 다양한 패치(patche)로 모일 개별 동물의 수는 각각에 이용 가능한 자원의 양에 비례한다고 명시하고 있다. 예를 들어, 패치 A에 패치 B보다 2 배 많은 리소스가 포함된 경우 패치 B에서보다 패치 A에서 약탈하는 개체가 2 배 더 많을것이다. 이상적인 자유 분포(IFD) 이론은 패치 사이에 동물의 분포가 리소스를 최소화할 것으로 예측한다. 경쟁과 체력을 극대화하기 위해서라고 이해한다.

- In ecology, an ideal free distribution (IFD) is a theoretical way in which a population's individuals distribute themselves among several patches of resources within their environment, in order to minimize resource competition and maximize fitness. The theory states that the number of individual animals that will aggregate in various patches is proportional to the amount of resources available in each. For example, if patch A contains twice as many resources as patch B, there will be twice as many individuals foraging in patch A as in patch B. The term "ideal" implies that animals are aware of each patch's quality, and they choose to forage in the patch with the highest quality. The term "free" implies that animals are capable of moving unhindered from one patch to another. Although these assumptions are not always upheld in nature, there are still many experiments that have been performed in support of IFD, even if populations naturally deviate between patches before reaching IFD. IFD theory can still be used to analyze foraging behaviors of animals, whether those behaviors support IFD, or violate it. (en)
