Summary
We introduce search profligacy, balancing cost versus success probability. Optimal search strategies, particularly with stochastic resetting, reveal complex, non-intuitive parameter dependencies for efficient target finding.
Area of Science:
- Physics
- Statistical Mechanics
- Physical Chemistry
Background:
- Search processes are fundamental in nature and technology.
- Quantifying search efficiency is crucial for optimization.
- Stochastic resetting introduces a mechanism to influence search dynamics.
Purpose of the Study:
- To define and analyze "search profligacy" as a metric for search efficiency.
- To determine optimal search strategies under resetting conditions.
- To investigate the phase transitions associated with optimal resetting parameters.
Main Methods:
- Formulation of search profligacy as a cost-probability competition.
- Minimization of profligacy to derive optimal search strategies.
- Analysis of diffusion with stochastic resetting and its parameter dependence.
Main Results:
- Optimal resetting amount exhibits complex, non-trivial dependence on model parameters.
- Observed classical continuous and discontinuous phase transitions.
- Identified tricritical points and nonstandard transitions like reentrant behavior and overhangs.
Conclusions:
- Search profligacy provides a framework for optimizing search processes.
- Stochastic resetting introduces rich phase diagram behavior in optimal search.
- The study reveals novel transition phenomena in optimized diffusion processes.

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...
