inctf_20

k-map-minimization

given a kmap (don't cares supported) it returns the reduced boolean expression for it.

linear_regression

Given a univariate Input output training data the program calculates the linear regression and outputs the equation of the line passing through these points with minimum error.

mangers_attack_on_rsa

performs the basic implementation of manger's attack as suggested https://research.kudelskisecurity.com/2018/04/05/breaking-rsa-oaep-with-mangers-attack/

multivariate_regression

Given a set of inputs corresponding to 1 output, the program calculates the multivariate regression for it. It also performs the 80 20 ratio system i.e it trains on the 1st 80% of the data and then test on the remaining 20% it then calculates the mean squared error and mean absolute error, also for a given input it finds the best combination of inputs it should consider to minimize the error
