Let two linear matroids have the same rank in matroid intersection.
A maximum linear matroid intersection (maximum linear matroid parity
set) is called a basic matroid intersection (basic matroid parity
set), if its size is the rank of the matroid. We present that
enumerating all basic matroid intersections (basic matroid ... more >>>

The seminal result of Impagliazzo and Rudich (STOC 1989) gave a black-box separation between one-way functions and public-key encryption: informally, a public-key encryption scheme cannot be constructed using one-way functions as the sole source of computational hardness. In addition, this implied a black-box separation between one-way functions and protocols for ... more >>>

We develop a framework for proving lower bounds on computational problems over distributions, including optimization and unsupervised learning. Our framework is based on defining a restricted class of algorithms, called statistical algorithms, that instead of accessing samples from the input distribution can only obtain an estimate of the expectation ... more >>>
