Inverse problems in geophysics involve determining the physical properties of the Earth’s subsurface (like density, velocity, or conductivity) based on indirect observations, such as seismic waves, gravity measurements, or magnetic fields. Unlike forward problems, where you start with a known model and predict the data (e.g., how seismic waves propagate through a given structure), inverse … Read more
Fourier Transform is a mathematical tool or operation that transforms or breaks down a function or a signal into its constituent frequencies. In essence, it decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. Think of it like a prism splitting light into a spectrum of colors—except … Read more
Lanchester’s Square Laws, formulated by British engineer and mathematician Frederick W. Lanchester during World War I, are a set of mathematical principles that describe the relationship between the combat effectiveness of opposing forces in warfare. These laws aim to quantify how the size and organization of military forces influence the outcome of battles, particularly in … Read more
Trading futures versus forex (foreign exchange) pits two dynamic, leveraged markets against each other, each with unique structures, opportunities, and challenges. Both attract traders seeking high returns, but they differ significantly in mechanics, accessibility, risk profiles, and focus. Let’s explore every angle—market structure, contracts, liquidity, volatility, trading hours, leverage, costs, risks, rewards, and suitability—to give … Read more
Trading stocks versus trading forex (foreign exchange) is a decision many investors and traders face, and each market offers distinct characteristics that cater to different goals, risk tolerances, and lifestyles. Let’s dive into a comprehensive comparison across various aspects—market structure, accessibility, liquidity, volatility, trading hours, leverage, costs, focus, risks, rewards, and more—to help you understand … Read more
The inverse geodesic problem is a concept in differential geometry and related fields, particularly on curved surfaces or manifolds. It involves finding a geodesic—a shortest path between two points—given certain constraints, but in reverse. Instead of starting with two points and finding the geodesic between them (the direct geodesic problem), the inverse problem typically involves … Read more
The Fourier Transform is a mathematical tool used to break down a function—typically a time-based signal—into its constituent frequencies. It transforms a signal from the time domain (where it’s expressed as amplitude over time) into the frequency domain (where it’s expressed as amplitude across different frequencies). This allows you to see the frequency components that … Read more
Linear Programming (LP): LP problems have an objective and all constraints that are linear functions of the decision variables. LP problems are intrinsically easier to solve than general nonlinear problems, as they have at most one feasible region with “flat faces” on its outer surface, and the optimal solution will always be found at a … Read more
This list reflects a blend of strategies that could be implemented or are already available in some form on Deriv’s platform, based on general trading bot concepts and user insights up to 2024. Always remember, trading involves risk, and no strategy guarantees profit. When considering these “bots” or strategies
Among all word pairs with confusing meanings and uses, i.e. and e.g. occupy a peculiar position. They are identical especially because they are two-letter abbreviations. They are, however, not to be used interchangeably because their meanings are different. To start with, i.e. is the abbreviation of the Latin phrase ‘id est’, which means ‘that is’ … Read more
