Extended General Malfatti’s Problem

Algorithms
Malfatti’s problem involves three circles (called Malfatti circles) that are tangent to each other and two sides of a triangle. In this study, our objective is to extend the problem to find 6, 10, … ∑1ni (n > 2) circles inside the triangle so that the ...

Global search method for solving Malfatti’s four-circle problem

Известия Иркутского государственного университета: Серия "Математика", 2016
We consider Malfatti’s problem formulated 200 years ago. In the beginning, Malfatti’s problem was supposed to be solved in a geometric construction way. In 1994, it was done by Zalgaller and Los for the original Malfatti’s problem using so-called greedy ...
