  2. Regula falsi - Wikipedia

    en.wikipedia.org/wiki/Regula_falsi

    The convergence rate of the bisection method could possibly be improved by using a different solution estimate. The regula falsi method calculates the new solution estimate as the x-intercept of the line segment joining the endpoints of the function on the current bracketing interval. Essentially, the root is being approximated by replacing the ...

  3. Unity of invention under the European Patent Convention

    en.wikipedia.org/wiki/Unity_of_invention_under...

    Under the former version of Rule 36 EPC, an objection of lack of unity of invention raised in a communication of the Examining Division could trigger a 24-month period for filing a divisional application, if the particular objection was raised for the first time. However, under the amended version of Rule 36 EPC which came into effect in April ...

    An alternative form of the parametrization that is sometimes useful is = [+]. This form can be derived using the change of variables = / ().We can use the product rule to show that = / (), then

  5. Linear interpolation - Wikipedia

    en.wikipedia.org/wiki/Linear_interpolation

    Linear interpolation on a data set (red points) consists of pieces of linear interpolants (blue lines). Linear interpolation on a set of data points (x 0, y 0), (x 1, y 1), ..., (x n, y n) is defined as piecewise linear, resulting from the concatenation of linear segment interpolants between each pair of data points.

  6. Integration by substitution - Wikipedia

    en.wikipedia.org/wiki/Integration_by_substitution

    In calculus, integration by substitution, also known as u-substitution, reverse chain rule or change of variables, [1] is a method for evaluating integrals and antiderivatives. It is the counterpart to the chain rule for differentiation , and can loosely be thought of as using the chain rule "backwards."

    Due to the latter issue, Traugott's rule can take advantage of the implication in assumption (4), using as the non-atomic formula in step (12). Using Murray's rules, the semantically equivalent formula e ∨ ¬ a ∨ ¬ a {\displaystyle e\lor \lnot a\lor \lnot a} was obtained as (7), however, it could not be used as p {\displaystyle p} due to ...

  9. Backtracking line search - Wikipedia

    en.wikipedia.org/wiki/Backtracking_line_search

    The method involves starting with a relatively large estimate of the step size for movement along the line search direction, and iteratively shrinking the step size (i.e., "backtracking") until a decrease of the objective function is observed that adequately corresponds to the amount of decrease that is expected, based on the step size and the ...
