1. *Less* and *the least* are used with adjectives and adverbs in the same way as *more* and *the most*. *Less* indicates a lower degree and *least* indicates the lowest degree. It's not possible to say *the less complicate*; we need to use the superlative here: *the least complicated*.  
2. *Less* and *the least* are used with adjectives and adverbs in the same way as *more* and *the most*. *Less* indicates a lower degree and *least* indicates the lowest degree. However, *complication* is a noun, not an adjective, and therefore we can't use it here.  
3. *Less* and *the least* are used with adjectives and adverbs in the same way as *more* and *the most*. *Less* indicates a lower degree and *least* indicates the lowest degree. The four-syllable regular adjective *complicated* shouldn't change its form. We need to use the superlative here: *the least complicated*.
