软计算可以是一种计算模型，它旨在解决涉及缠结的不确定、不精确和近似解的非线性问题。这些类型的问题都被认为是现实生活中的问题，只要需要类人的智慧来解决它。
硬计算是一种古老的计算方法，它需要护理助理准确地声明分析模型。硬计算方法的结果是有保证的、确定的、正确的结果，并使用数学模型或算法规则定义明确的管理行为。它处理需要精确输入文件连续的二进制和清晰的逻辑。硬计算无法找到现实世界问题的解决方案。
软计算和硬计算的区别：
| S.NO | Soft Computing | Hard Computing |
|---|---|---|
| 1. | Soft Computing is liberal of inexactness, uncertainty, partial truth and approximation. | Hard computing needs a exactly state analytic model. |
| 2. | Soft Computing relies on formal logic and probabilistic reasoning. | Hard computing relies on binary logic and crisp system. |
| 3. | Soft computing has the features of approximation and dispositionality. | Hard computing has the features of exactitude(precision) and categoricity. |
| 4. | Soft computing is stochastic in nature. | Hard computing is deterministic in nature. |
| 5. | Soft computing works on ambiguous and noisy data. | Hard computing works on exact data. |
| 6. | Soft computing can perform parallel computations. | Hard computing performs sequential computations. |
| 7. | Soft computing produces approximate results. | Hard computing produces precise results. |
| 8. | Soft computing will emerge its own programs. | Hard computing requires programs to be written. |
| 9. | Soft computing incorporates randomness . | Hard computing is settled. |
| 10. | Soft computing will use multivalued logic. | Hard computing uses two-valued logic. |
