The conventional mechanisms transmitted force and displacement through rigid members (high stiffness) and traditional joints (with high softness), where recently, researchers have come up with new systems called compliant mechanisms that transfer power and mobility through the deformation of their flexible members. One of the most frequently used approaches for designing compliant mechanisms is topology optimization. Extracting the optimal design of a displacement amplifying compliant mechanism using the modified Invasive Weed Optimization (MIWO) method is the current study's main novelty. The studied mechanism is a compliant micro-mechanism that can be used as a micrometric displacement amplifier. The goal of this synthesis is to maximize the output-to-input displacement ratio. In this research, a new random step is added to the Invasive Weed Optimization (IWO) method; the new seeds can be spread farther from their parents, which can be improved the algorithm's abilities. The results show that the use of the modified IWO algorithm for this problem has led to a significant improvement over the results from similar articles.

常规机构通过刚性构件（高刚度）和传统关节（具有较高的柔软性）传递力和位移，最近，研究人员提出了一种新的系统，称为顺应性机构，该系统通过其柔性构件的变形来传递动力和活动性。用于设计兼容机制的最常用方法之一是拓扑优化。使用改进的有创杂草优化（MIWO）方法提取位移放大顺应机构的最佳设计是当前研究的主要创新之处。所研究的机制是可以用作测微位移放大器的顺应性微机制。该合成的目标是使输出与输入的位移比最大。在这项研究中 将新的随机步骤添加到“侵入性杂草优化”（IWO）方法中；新种子可以从父母那里传播得更远，从而可以提高算法的能力。结果表明，针对该问题使用改进的IWO算法已导致对类似文章的结果进行了重大改进。
