**Soft Computing** could be a computing model evolved to resolve the non-linear issues that involve unsure, imprecise and approximate solutions of a tangle. These sorts of issues square measure thought of as real-life issues wherever the human-like intelligence is needed to resolve it.

**Hard Computing** is that the ancient approach employed in computing that desires Associate in Nursing accurately declared analytical model. the outcome of hard computing approach is a warranted, settled, correct result and defines definite management actions employing a mathematical model or algorithmic rule. It deals with binary and crisp logic that need the precise input file consecutive. Hard computing isn’t capable of finding the real world problem’s solution.

**Difference between Soft Computing and Hard Computing:**

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. |
