“假设”
用英语怎么说？

In 2004, two mathematicians hypothesized a novel kind of sandwich to understand complex networks. In graph theory, graphs consist of vertices and edges that model systems ranging from social connections to neural circuits. Researchers sought to investigate regular graphs-structures where every vertex has an identical degree, rendering them ubiquitous yet notoriously difficult to analyze. Their ambitious goal was to mathematically embed these intricate structures between two simpler binomial graphs, where edges form independently at random. Demonstrating that such an arrangement existed would prove that key mathematical properties of the more tractable binomial graphs naturally extend to regular graphs.

2004年，两位数学家假设了一种新型“三明治”，用以理解复杂网络。在图论中，图由顶点和边组成，可模拟从社交联系到神经回路的各种系统。研究人员试图探究正则图--即每个顶点度数都相同的结构，这种结构无处不在却极难分析。他们雄心勃勃的目标是将这些错综复杂的结构在数学上置于两个更简单的二项式随机图之间，后者的边是独立随机生成的。证明这种构造的存在将表明，更易处理的二项式图的关键数学性质可以自然延伸至正则图。
