ISSN 0743-166X) with K. G. Ramakrishnan, to describe a new class of Algorithm. This opened a new research direction in theoretical science. He found that A*Prune is comparable to the current best known-approximate algorithms for most randomly generated graphs. The algorithm constructs paths, starting at the source and going towards the destination. But, at each iteration, the algorithm is rid of all paths that are guaranteed to violate the constraints, thereby keeping only those partial paths that have the potential to be turned into feasible paths, from which the optimal paths are drawn.

Liu also proposed a special class of Optical devices called SPIDER (2001, ISSN   1089-7089); optical routers, dense wavelength division multiplexing (DWDM) systems, and cross-connects of unprecedented capacities. Liu and his colleagues are developing techniques for efficient and reliable optical network design, covering decentralized dedicated protection to shared path-based mesh restoration. [22]

The 1989 Tiananmen Square protests and massacre were the first of their type shown in detail on Western television. The Chinese government's response was denounced across the world; a report by the U.S. State Department said: "Foreign governments have expressed near universal revulsion over the crackdown although a few exceptions have supported China's approaches. Negative reactions range from punitive measures by Western countries to private criticisms in the East." Specifically, it said: "China's credentials as a socialist reformer were being called into question not only by Western European communists but also by progressives in Eastern Europe and, to a lesser extent, the Soviet Union." Notably however, many Asian countries remained silent throughout the protests; the government of India responded to the massacre by ordering the state television to pare down the coverage to the barest minimum, so as not to jeopardize a thawing in relations with China, and to offer political empathy for the events. Criticism came from both Western and Eastern Europe, North America, Australia and some east Asian and Latin American countries. North Korea, Cuba, Czechoslovakia, and East Germany, among others, supported the Chinese government and denounced the protests. Overseas Chinese students demonstrated in many cities in Europe, America, the Middle East, and Asia against the Chinese government.

The Beijing Students' Autonomous Federation was a self-governing student organization, representing multiple Beijing universities, and acting as the student protesters' principal decision-making body during the 1989 Tiananmen Square protests. Student protesters founded the Federation in opposition to the official, government-supported student organizations, which they believed were undemocratic. Although the Federation made several demands of the government during the protests and organized multiple demonstrations in the Square, its primary focus was to obtain government recognition as a legitimate organization. By seeking this recognition, the Federation directly challenged the Chinese Communist Party's authority. After failing to achieve direct dialogue with the government, the Federation lost support from student protesters, and its central leadership role within the Tiananmen Square protests.
