On Circuit Complexity of Parity and Majority Functions in Antichain Basis

چکیده

We study the circuit complexity of boolean functions in a certain infinite basis. The basis consists of all functions that take value 1 on antichains over the boolean cube. We prove that the circuit complexity of the parity function and the majority function of n variables in this basis is b 2 c and ⌊ n 2 ⌋ +1 respectively. We show that the asymptotic of the maximum complexity of n-variable boolean functions in this basis equals n.

Lecture 11 : Circuit Lower

There are specific kinds of circuits for which lower bounds techniques were successfully developed. One is small-depth circuits, the other is monotone circuits. For constant-depth circuits with AND,OR,NOT gates, people proved that they cannot compute simple functions like PARITY [3, 1] or MAJORITY. For monotone circuits, Alexander A. Razborov proved that CLIQUE, an NP-complete problem, has expo...

A new circuit model for the Parameters in equations of low power Hodgkin-Huxley neuron cell

In this paper, α and β parameters and gating variables equations of Hodgkin-Huxley neuron cell have been studied. Gating variables show opening and closing rate of ion flow of calcium and potassium in neuron cell. Variable functions α and β, are exponential functions in terms of u potential that have been obtained by Hodgkin and Huxley experimentally to adjust the equations of neural cells. In ...

2 Monotone Functions and Monotone Circuits

In the last lecture we looked at lower bounds for constant-depth circuits, proving that PARITY cannot be computed by constant-depth circuits, i.e. PARITY / ∈ AC0. General circuit lower bounds for explicit functions are quite weak: the best we can prove after years of effort is that there is a function, which requires circuits of size 5n − o(n). In this lecture we will examine what happens if we...

Lecture 5: Razborov-Smolensky Lower Bounds for Constant-Depth Circuit with MODp Gates

In this lecture, we will talk about circuit lower bound for constant-depth circuit with MODp gates. Using switching lemma, we can prove exponential size lower bound for constant-depth circuit computing parity and majority. What if parity (=MOD2 gates) are allowed? It was conjectured that majority still needs exponential size to compute in constant-depth circuit. Razborov (1987) solves this conj...

A Duality Between Depth-Three Formulas and Approximation by Depth-Two

We establish an explicit link between depth-3 formulas and one-sided-error approximation by depth-2 formulas, which were previously studied independently. Specifically, we show that the minimum size of depth-3 formulas is (up to a factor of n) equal to the inverse of the maximum, over all depth-2 formulas, of one-sided-error correlation bound divided by the size of the depth-2 formula, on a cer...
