iteration point的用法和樣例：
例句
- The smaller the value of the merit function is, the closer the iteration point is to the solution.
當價(jià)值函數的值越小時(shí)，迭代點(diǎn)越靠近最優(yōu)解。 - Furthermore, the model will keep iterating within the feasible region whenever the iterative point is feasible, and become feasible decreasing directions method.
進(jìn)一步地，一旦迭代點(diǎn)進(jìn)入可行域，模型就能保持在可行域內迭代，成為可行下降類(lèi)算法。
